Police have released a composite sketch of the knife-wielding man who attacked a pregnant woman outside her Hallam home on Tuesday, and are asking the public's help in identifying the attacker.

The woman, whose name has not been released, was slashed twice as she walked out of her home in the first block of East Forry Avenue about noon, according to Hellam Township Police Chief Mark Sowers.

She suffered a scratch on her face and a wound to her arm that required stitches, he said.

The woman was letting out her dogs when she encountered a man at her door, according to Sowers.

He attacked her, then fled the scene, police said.

Police searched the area but were unable to find the man, Sowers said.

"At this time we have no leads," he said.

Description: The attacker is described as a thin white male between 18 and 20 years old, with a pale complexion. He is about 5-feet-11 and weighs about 120 to 140 pounds, police said. At the time of the attack he was wearing a black hooded sweatshirt, Sowers said.

The chief said people who see anything unusual should contact police right away.

"(Residents) don't need to be frightened, but they always need to take extra safety precautions and be vigilant," Sowers said.

Anyone with information about the man's identity is asked to call Hellam Township Police at (717) 434-1310.
