A teenage boy has been arrested in relation to an incident where youths were seen throwing eggs at buses and drivers.
The 16-year-old boy from Crawley has been arrested on suspicion of common assault and criminal damage after the incident in Broadfield on October 7.
He has been bailed until November 25 while investigations continue.
PC Anthony Cheeseman said: "We believe there are a number of people involved and we are working to identify those involved. We have also been working closely with Metrobus.
"If anyone has any information which will help us with our investigation please come forward either to police directly or to the independent charity Crimestoppers anonymously on 0800 555 111. Also if victims have not reported anything which has happened they are urged to get in touch."
