Police have arrested a man over reports of indecent behaviour in the presence of two young girls on two buses in Crawley.
Following a public appeal on July 26, during which police released a photo of the suspect, officers arrested a 24-year-old man the next day on suspicion of outraging public indecency.
He was interviewed and released on bail with conditions until August 24 while enquiries continue.
The two incidents happened on the number 3 bus route, one on June 29 in Gosspos Green and one on July 2 in Pound Hill. Neither of the girls were harmed and were able to leave the buses safely.
Detective Inspector Ali Hutchings said: "Anyone who has any other information, is asked to report online or call 101, quoting serial 1093 of 29/06."
