A juvenile suspected of groping a woman walking on a sidewalk and then trying to pull her off a popular trail was arrested on Tuesday in Hopkins.

Doorbell surveillance video from about 7 p.m. Thursday shows the suspect on a bicycle first grabbing the woman's buttocks near the intersection of NE. Lake Street and N. Tyler Avenue before continuing to follow her, said Police Sgt. Michael Glassberg.

Once the woman, in her early 30s, was on the nearby Cedar Lake Trail, "he got off his bike and tried to pull her off the trail," Glassberg said.

The woman fought him off, and the suspect fled, the sergeant said.

"The trails are safe," Glassberg said. "They are used a lot."

Glassberg said the suspect was not someone the woman knew. His identity will not be released because of his age, according to Glassberg.

Police offered a $1,000 reward to find the suspect.
