Concord police say they're investigating a reported random attack of a resident on her back porch Saturday night.

Police were called for the incident to Iron Works Road near Martin Field and Madison Street, they said.

There, the resident told police she was on her back porch just before 10 p.m. when a stranger appeared from a wooded area, authorities reported.

“The stranger ran towards the victim, pushed her down by the throat and struck her multiple times,” police said in a press release. “When the attack ended the suspect ran out of the yard in an unknown direction.”

The attacker is described as a white man, tall and thin”with an unkempt, scraggly beard,” police said. He’s believed to be in his late 30s, and was wearing a green and white plaid shirt at the time.

Earlier that evening, a neighbor on Iron Works Road reported seeing someone walking through backyards, according to authorities.

Police are asking the public to help identify the alleged attacker, and those who may have seen suspicious behavior between 8 p.m. and midnight are asked to call police. Residents are also asked to check their home video cameras.
