A CCTV appeal has been launched after a man committed an indecent act on a bus.

The victim, a woman in her 20s, boarded the double-decker 292 bus on Theobald Street, Borehamwood, near to the junction of Beech Drive at around 11am on Friday, November 14.

A man then boarded the bus outside Specsavers on Shenley Road, and told the driver he wanted to go to the Fairway stop in Barnet before sitting near the victim on the top deck.

The man then committed an indecent act.

After the woman went downstairs and told the driver, he stopped the bus near Morrisons to call police but the offender ran off before officers arrived.

Police would like to speak with the man pictured as he may have information which could assist the investigation.

Anyone who is able to assist in identifying the man pictured should contact the Herts Police non-emergency number 101
