Regional transport group Veolia, which operates buses and trains in the south of the country, plans to give train conductors test tubes to collect saliva if they are spat at for DNA research, the AD reports on Monday.

‘We are looking at what is legally acceptable,’ spokesman Roland Becx told the paper. ‘It is a serious problem and we must take action quickly.’
The company is also considering allowing sniffer dogs to check buses and trains for drugs and install security gates.
