Police are appealing for help to trace a man who was riding a mountain bike in Beccles after a man in his 40s was sexually assaulted.

The incident happened on Saturday, June 11, at around 11pm as the man in his 40s walked home along Kemps Lane. He stopped to look at his phone and when he looked up he saw the man just in front of him standing astride the bike.

The man is described as white, in his 30s to 40s, around 5ft 9ins to 5ft 10ins tall, with short dark receding hair that was brushed forward, wearing shorts and a light coloured T-shirt and trainers.

The offender then made a grab for the man's groin area, making contact before cycling away. Moments later the offender returned on his bike and made a second grab and again made contact.

Police are asking anyone who may have any information about the incident or the man involved to call Suffolk Police on 101, quoting crime number 40133/16.
