Sandy Springs police are looking for a man they say sexually assaulted a woman before stabbing her with a switchblade.

According to a police report, the woman was walking near an office complex along Hammond Drive on October 19 when a man who said he was a security guard stopped and talked to her. The man then grabbed her breasts and exposed himself to her.

He attempted to assault her again, but this time pulled out a switchblade and stabbed her multiple times in her left hand, according to the report.

The woman fought her attacker, but he managed to get away.

Looking for help, the victim walked toward Ga. 400 and Hammond Drive and was spotted by two brothers, Dan and Pete Poisson.

The men were driving to work and had just gotten off the highway when they saw her, Channel 2 Action News reported.

“The young lady was out in the street, waving her arms,” Dan Poisson told the news station. “I saw that she was bleeding really badly.”

One brother put pressure on her wound. The other looked out for the attacker.

“God put us where we were supposed to be,” Pete Poisson told Channel 2. “We’ve been trained on how to do things and help people, and it’s just our nature that we go out and help folks.”

The woman is in a cast, but told the news station she thinks fighting off the man kept her from more harm.

“There are hundreds, plural, of stitches. (The switchblade) cut through the muscle, tendons, ligaments, nerves, and I nicked an artery,” she said. “That’s how my hand got sliced up, but I also think that’s what saved me. He didn’t get what he was after.”

Police told Channel 2 there were few leads on the man’s identity.
