Update: Photos of possible suspect released.

Boston Police report two women were grabbed and stabbed early this morning, possibly by the same man.

In both cases, the women were grabbed from behind, police say.

In the first case, a woman walking in the area of Vancouver Street and Huntington Avenue told police:

The suspect jumped out of the bushes, grabbed her and attempted to sexually assault her. The female victim was stabbed in the leg, but was able to escape. Her injuries are non-life threatening. The suspect is described as a white male, in his 20s, blonde or brownish hair, 6' feet, wearing a blue plaid shirt and khaki shorts.

Around 2:50 a.m., another woman was grabbed from behind and knocked to the ground about a mile away at Huntington Avenue and Parker Hill Street:

The victim was stabbed in the hand, but able to escape. Her injuries are non-life threatening. The suspect is described as a white male, in his early 20s, brownish wavy hair, 5'7-6 feet, wearing a white or grey hoodie and blue jeans.

Police taped off a large area around Huntington Avenue and Wait Street this morning as they investigate the attacks. "Police and big crowd of people gathered [near Wait]," Reed Van Dyck tweeted around 9 a.m.

Last month, three women were sexually assaulted on Beacon Hill.
