A British Airways flight attendant was found naked in an onboard toilet while under the influence of drugs, a court has heard.

Haden Pentecost, 41, was working on a flight from California to London when he started to become agitated and was described as "sweating" and "babbling".

A blood test later revealed Pentecost had methamphetamine and amphetamines in his system.

Pentecost, who has been sacked, pleaded guilty at Uxbridge Magistrates' Court to performing an aviation function while impaired by drugs.

The court heard Pentecost had to be stood down by his manager when he failed to help with any pre-flight safety checks.

After complaining of cramps and saying he had to change his clothes, he locked himself in one of the toilets - where a colleague later found him naked and oblivious to the fact, the court was told.

He had dilated pupils, a high heart rate, and had to be checked every 20 minutes until the plane arrived at Heathrow. Paramedics then took Pentecost to hospital.

Pentecost, of Basingstoke, was granted bail and will be sentenced at Isleworth Crown Court at a later date.

British Airways has been approached by the BBC for comment.
