Transit Police say a South Boston man was charged with disorderly conduct Friday after officers discovered him "train surfing" from the back of an inbound Red Line train in Quincy.

Police say they found Justin Green, 29, hanging onto the top roof rail from the rear of the train, as it was pulling out of North Quincy around 5:30 p.m. A witness then told police he had seen Green doing the same thing at Wollaston.

Police say Green objected to being charged because he has "a God given right to do anything he wants" and that the only person that would have been harmed was himself.

Police, however, say Green forced a halt in Red Line service while they got him off the train.

They add that in addition to disorderly conduct, Green was packaged into a cruiser for a ride to Transit Police headquarters because he was wanted for evading jury duty.

Innocent, etc.

Boston Police report three men were shot at a party at 31 Hecla St. around 11:30 p.m. on Friday.

One of the victims suffered life-threatening injuries; the other two managed to run to Adams Street a half block away, where police found them.

Boston Police report the homicide unit and the Boston Fire arson unit are now both investigating the Sunday-morning fire that left one BU student dead and sent 15 other people - including six firefighters - to the hospital.

The Herald reports Inspectional Services is investigating how 18 people - half of them BU students - came to be crammed into what is officially a two-family house at 87 Linden St. City Councilor and mayoral candidate Mike Ross also wants to know more about the house - he wrote a city ordinance that bars more than four students from living in a single unit.

Boston University today identified the student as Binland Lee, set to graduate in September.

UPDATE: Dorchester man arrested.

Somebody was found shot this morning on Brook Street. The victim was taken away in bad enough shape to have the homicide unit called in, just in case. The victim was found just a few doors down from the scene of a fight that ended in gunfire last night.

It's hard to imagine how many miles of train tracks used to exist within Boston city limits (let alone how few will be left once Harvard gets around to ripping out the Allston yard). Here we see the train yard in front of Commonwealth Pier in South Boston, sometime shortly after World War I. Today, the pier is better known as the World Trade Center and the tracks have mostly been replaced by highway ramps, parking lots and surface roads. Nearby is Fan Pier, named for the way the train tracks there fanned out toward the water.

The Back Bay used to have its own large train yard - since replaced by the Prudential Center and the Massachusetts Turnpike:

A flood of complaints poured in late this afternoon from downtown, the Back Bay and Beacon Hill, where a large contingent of people on dirt bikes, motorcycles and ATVs briefly took over the streets.

At 5:26, Gabe tweeted:

A legit gang of a couple dozen 4wheelers and dirtbikes just ran the red light at Washington & Essex street...confused.

At 5:47, Caitlin tweeted:

What's up with the gang of dirt bikes, ATV's and motorcycles on Newbury St? Weaving in and out of cars with no helmets?

Bill Ilott reports counting 30 riders tonight and says this is the third Sunday in a row for the activity.

Helmetless dirt-bike and ATV riders have long been the scourge of streets such as Blue Hill Avenue.

Stanley Staco reports a man was shot around 5:15 p.m. at 535 Washington St. Because of the victim's condition, homicide detectives were summoned, just in case.

A car spotted fleeing from the scene was registered to somebody in Roslindale, and about an hour later, police began investigating a car and possible witnesses at the McDonald's on American Legion Highway in Roslindale.

The Boston Fire Department reports a fire that broke out around 6:30 a.m. at 87 Linden St. killed one resident, injured nine more and sent six firefighters to the hospital. BU Today reports the dead person was a BU student.

The Boston Fire Department says the injured residents and firefighters are expected to live. The department reports one resident jumped out a window to escape the flames; three others were brought down on ladders.

WBZ reports three firefighters were injured falling from the second to the first floor.

Police officers patrolling South Boston tonight were urged to be on the lookout for a white trolley party bus, careening through the streets of the neighborhood, its passengers throwing eggs at pedestrians and yelling at them.

Around 9 p.m., Matthew Gaskill reported spotting the eggmobile on East Broadway, heading toward the city.

UPDATE, 10:52 p.m.: Amanda Hitt reports seeing a white trolley bus with "what looked like an egg yolk stain on the side" parked on Canal Street.
