OLD FIELD - Police hope a sketch they've released will help track down the man who they say attacked a jogger in Old Field this week.

Investigators say a woman was running on North Grey Road Tuesday morning when a man grabbed her from behind and groped her.

The suspect was spooked off by a passing motorist, who stopped to help the victim.

He is described as a man between 17 and 21 years old and about 5 feet 6 inches tall with a thin-to-medium build. Anyone with information is urged to call Suffolk Crime Stoppers at 1-800-220-TIPS.Police: Female jogger attacked in Old Field
