Boston Police report arresting a man they say tried beating up a BPL employee on Boylston Street last night after the worker asked him to leave the building for causing a ruckus.
Police say William Zaniboni, 49, became "irate without cause and began yelling" at the worker, who demanded he leave the building, shortly before the library's 9 p.m. scheduled closing:
When the victim asked the suspect to leave the building, the suspect indicated that he would be waiting outside for him. A short time later when the victim was leaving, the suspect approached him and struck him in the face with his clenched fist one time. The victim then proceeded to defend himself by bringing the suspect to the ground. Once on the sidewalk, the suspect produced a spray can of an undetermined chemical agent believed to be mace and sprayed the victim in the face. The suspect then walked towards Exeter Street but returned to the scene a short time later where he was placed in custody without incident after being positively identified. Officers canvassed the area but were unable to recover the spray bottle used by the suspect during the altercation.
Zaniboni was charged with assault and battery by means of a dangerous weapon and assault and battery, police say.
