Tube driver in breath test arrest
A Tube driver has been arrested after failing to supply a breath sample when concerns were raised that he might have been under the influence of alcohol.
Police were called to Queensbury station, in north-west London, at about 15:00 GMT on Saturday.
A 50-year-old man was arrested under the Transport and Works Act, British Transport Police (BTP) said.
He was released on bail, to return to a police station on 2 April pending further inquiries.
A TfL spokesman said: "On Saturday afternoon a train operator was relieved from duty after concerns were raised about his conduct.
"The train operator was subsequently taken into custody by British Transport Police. The member of staff is suspended while investigations by ourselves and the BTP are continuing."
