Transit Police report  a man stopped for questioning at Park Street for allegedly nabbing another Green Line rider's phone turned out to be wanted on a warrant for indecent assault and battery on another MBTA train.
Upon arrival officers were met by the reporting party who stated as he was traveling on a Green Line westbound train another passenger, later identified as Dane Mullin 26 of Boston, chose to sit in between the reporting party and another female passenger despite the fact there were several other available seats. Prior to this Mullin oddly walked back and forth through the train car before taking a seat. As the train was approaching Park Street the reporting party got up from his seat and began making his way to the doors. He suddenly realized his cell phone was missing from his jacket pocket. He suspected Mullin had stolen his phone and confronted him. An MBTA employee who observed what was taking place contacted Transit Police.
Police say they did not find the other passenger's phone on Mullin, but placed him under arrest for the warrant. Mullin, a former Salem resident who now lists the Pine Street Inn as his home address, has a sex-offender record  dating to when he was 17 and was convicted for grabbing a woman walking down the street in Salem.
