Transit Police report arresting a Dorchester woman on charges she threw hot coffee in a T worker's face around 9:30 p.m. yesterday.

Police say Janet Bourke, 61, of Dorchester, was trying to get into Broadway on the Red Line without paying when the worker spotted her and tried to stop her.

The victim was treated at the scene by Boston EMTs.

Police say Bourke was charged with assault and battery with a dangerous weapon. During booking, police say, she punched an officer in the face, which is good for a separate charge of assault and battery on a police officer.

Innocent, etc.
