Police are looking for a man who poured a bottle of urine on a female passenger as she sat waiting for her train to depart.
The victim had sat down beneath an open window on the 20.46 Plumstead to Greenwich service when she felt the liquid running down from her head onto her clothes.
“The horrified woman recognised the smell to be urine,” said PC Tracy Mesher.
“She realised that the liquid had come from a drinks bottle which had been placed through the window she was sitting by.”
The victim seized the bottle and later handed it in to police.
Following the incident on May 24, British Transport Police (BTP) have now released a CCTV image of the suspect.
PC Mesher added: “This was a sickening experience for the victim, who was understandably left upset by what happened to her.
“We would like to speak to the man pictured as we believe he may be able to help us with our enquiries into this incident.
