An 88-year-old man from Abbots Langley has been arrested in connection with a sexual assault of an 11-year-old boy on a bus in Watford.
He has since been released on conditional bail.
Police are continuing to investigate the incident and are appealing to people who reportedly intervened during the incident to get in contact.
The incident happened on the 320 bus – travelling from Watford Junction railway station to the Dome roundabout – sometime between 3.30pm and 3.50pm on Monday, March 7.
An 11-year-old boy was reportedly touched inappropriately by another passenger on the bus, and it’s believed several other passengers witnessed what happened and intervened.
PC Rory Farmer, from the Watford Local Crime Unit, said: “We are very keen to trace the people who we believe went to the victim’s aid.
“We have been carrying out extensive enquiries into this incident since it was reported to us, as well as supporting the victim and liaising with the bus company and have made an arrest in connection with our inquiry.
“We have now reached a point in our investigation where we’re reaching out to the public for help in tracing those who intervened, as we believe they will have vital information for us.
“Could it have been you, or perhaps a friend? Do you remember travelling on the 320 bus during the specified times that day? If you have any information that you think could help us with our investigation – however small – please contact us as soon as possible.”
