LONDON -- Two women were arrested at Liverpool airport for trying to board a plane with a dead body, police said on Tuesday.

The pair, aged 41 and 66, had put the dead man into a wheelchair and put sunglasses on him, and were trying check in for a flight to Berlin on Saturday.

But airport staff became suspicious, and the two women -- both German nationals who live in Oldham, Greater Manchester -- were arrested on suspicion of "failing to give notification of death."

They have been released on bail until June 1, police said.

A spokesman for Manchester Police said: "At 11am on Saturday April 3, 2010, police at Liverpool John Lennon Airport were alerted to the death of a 91-year-old man in the terminal building.

"The coroner has been informed and police are continuing with their inquiries."

A post-mortem examination is due to take place over the next few days.
