A Good Samaritan who helped a teenage boy after he was attacked is being sought by police.
The 17-year-old was assaulted in Twechar towards the end of last year.
CID officers have made a fresh appeal to try to trace the driver who picked him up after the incident.
A CID spokesman said: “Following the attack about 11am on September 14, the victim was picked up by an unknown male passing in a blue car who stopped to help.
“This male then drove the victim home. We are keen to identify the driver and speak to him.”
If you were the driver or know him, contact DS David MacGregor at Kirkintilloch CID by calling 101.
