Bus drivers across the West Midlands have been given 'spit kits', mini DNA devices to help police track anyone who spits at them or fellow passengers.
The kits given by police are made up of swabs, gloves and special bags allow staff to collect saliva samples to be sent for forensic analysis.
So far this year there have been 88 reported cases of people spitting on regional buses.
Following a trial on Birmingham City Centre buses several offenders have already been traced including a 24-year-old man who was jailed for 12 weeks after spitting at a bus driver.
