Bosses of a Sheffield bus firm have praised detectives for arresting two yobs who held up drivers with a hammer and gun.
Aldridge, of no fixed abode, and Waby, of Ironside Road, Gleadless, stole cash from a driver after threatening him with a hammer.
They also demanded cash from another driver after threatening him with a gun.
Aldridge pleaded guilty to robbery, attempted robbery, possession of an offensive weapon and possession of an imitation firearm with intent to commit an offence, and Waby admitted robbery and attempted robbery.
They are to be sentenced next month.
A First spokesman said: “We want to thank the community and police for their support in bringing those responsible to justice.
“They were isolated incidents which were treated very seriously. We will not tolerate threats of violence against staff or customers.
Detective Constable John Briers said: “Bus drivers provide an invaluable service to the public and they should be able to provide this service without fear of attack.
“These incidents had an impact on the local community due to the fact that the buses stopped servicing Raeburn Road terminus during hours of darkness. We are very pleased that those responsible have been brought to justice.”
