Sexual assaults on Hackney and other London bus routes have led to the launch of an appeal asking the public to help identify people of interest.

The five images detectives have released relate to separate incidents that took place in different parts of the city between March and July. They are not believed to be connected.

Transport for London's (TfL) head of transport policing and community safety, Mandy McGregor, says there are around 2,500 police, community support officers and TfL enforcement officers patrolling the capital's transport system and it has an extensive network of CCTV cameras.

And while police say the level of crime on London’s transport network is generally low and advances in technology, including CCTV and the increase in electronic payment, mean offenders are often quickly caught, there are cases where it is not possible to identify a suspect using technology alone.

On these occasions, the public can play a vital role in identifying people of interest.

“No one should be subjected to unwanted sexual behaviour on our transport network and we are absolutely determined to stamp it out," Ms McGregor said.

"These incidents on London’s buses are appalling and we are working closely with the police to ensure these offenders are caught and brought to justice as soon as possible."
