POLICE are urging a dog walker to come forward who may hold vital clues to the indecent assault on a 20-year-old woman in Bromsgrove.

The victim was grabbed and thrown to the floor by the attacker as she walked along an alleyway between Grafton Crescent and Austin Road on Thursday night.

Her clothing was ripped and she had a graze to her face but the man ran off towards Grafton Crescent after being disturbed.

Officers want to hear from a man walking his dog and two witnesses standing at a bus stop by St Andrew's Church.

Call police on (01527) 584888 or Crimestoppers on 0800 555111.
