Three recent sexual assaults in and near the Mount Pleasant area of Northwest Washington may be related, the D.C. police said Sunday night.

In all three, a female victim was groped; in two the assailant approached from behind and in one a struggle broke out, and the victim was stabbed. All occurred around 2 or 3 a.m. and were “similar in nature,” police said.

The first assault occurred Wednesday as the victim was walking on Mount Pleasant Street. A man tried to engage her in conversation, and when she turned onto the 1700 block of Kenyon Street, police said, he put his arms around her and groped her beneath her clothing.

In the second attack, on Saturday, the victim was walking in the 1300 block of Oak Street when the attacker, armed with a knife, approached from behind, grabbed her around the neck and groped her.

She struggled and was stabbed, police said.

In the most recent attack, a woman walking in an alley in the rear of the 1700 block of Park Road saw someone following her. He placed his arms around her waist and groped her before she finally fled.

Police said the suspect in each of the incidents was described as Hispanic, in his 20s or early 30s. In the last two incidents, police were told that the assailant was about 5 feet 4.

Police said anyone with information should call them at 202-727-9099.
