A MOTHER and her young daughter were threatened by a gang of unruly teenagers on a bus.

The youths reportedly acted abusively to other passengers and were shouting and swearing on board the service from Brighton to Shoreham.

When the woman and her child got up to leave the bus, one said he would hurt them if they complained about the group’s behaviour.

British Transport Police (BTP) officers believe the person in the image, right, may have information which could help the investigation.

The incident happened between 6pm and 7pm on Sunday, December 23 but police have only just released this image.

Anyone who knows the individual is asked to contact BTP by texting 61016 or by calling 0800 405040 quoting e reference 43 of 24/12/18.
