A CCTV image has been released after a pregnant woman was punched and spat at on board a stationary train at an Essex station.

Police would like to speak with the woman pictured in connection with the incident, which happened around 7.30pm on Thursday, April 18 at Clacton-on-Sea station.

The 19-year-old victim was approached by another woman who then became aggressive towards her and punched her in the face and spat at her.

The victim did not know the woman and was left with bruising to the cheek.
