The Boston Police Department is investigating two separate incidents of indecent assault and battery near the Ashmont T station on Friday and Monday.

According to police, a woman was walking from Ashmont station around 12:20 a.m. on Friday when a black man, possibly Jamaican, began talking and flirting with her:

"The victim began to feel uncomfortable when the male grabbed her from behind placing his hand around her head and attempted to retrieve her cell phone. The victim was then pushed and sustained a scratch to her forehead and next to her right eye. The victim stated when the suspect placed his hand around her head she bit his thumb. The victim also stated the male groped her buttocks and then fled down Burt Street towards Washington Street.:

The attacker is described as possibly Jamaican due to his accent, about 5'5" and in his mid-20s. He was dressed in all black and wore a do-rag.

Around 7:00 a.m. Monday, a woman jogging north on Dorchester Avenue near the T stop noticed a man walking toward her, police say:

"The victim further stated that as she passed the suspect, he nudged her with his elbow, and subsequently grabbed and squeezed her buttocks. The victim reported she continued to run north on Dorchester Avenue, and the suspect changed direction and began casually walking north toward Ashmont Station."

This attacker was described as a light-skinned black or Hispanic male in his 20s or 30s, thick build, 5'9" or 5'10" with black or brown curly hair. He wore an oversided white T-shirt and black pants and had white ear buds in during the attack.
