An airline pilot has been charged after being arrested at London's Heathrow Airport on suspicion of being drunk.

Police said 51-year-old Erwin Vermont Washington, of Lakewood, Colorado, US, was charged with exceeding the proscribed alcohol limit.

He was released on bail and will appear in court again next week.
