Detectives have appealed for information to help identify a man who exposed himself to teens on two London buses.
An 18-year-old woman was left horrified after the man began performing a sex act on himself on the route 263 bus heading towards Barnet last October.
She told the bus driver and the man was told to leave the bus.
The second incident took place about 8.20am on October 7 after two 16-year-old girls boarded a bus travelling towards Waterloo Station.
The man boarded the bus near The Roundway in Wood Green and later exposed himself before carrying out a sex act on himself.
The bus driver later told the man to leave the vehicle.
The suspect has been described as black, aged 25 to 30, and about 6ft tall.
