A British tourist drowned after falling from a boat in Amsterdam, police said today.

The 27-year-old Scottish man was on a hotel boat docked in the city's Sumatrakade waterfront area when he fell overboard.

Two police officers and a fellow passenger dived in to try to rescue him, but he could not be found.

His body was later recovered by fire service divers.

A police investigation is under way into the incident which happened around 11pm on Saturday.

A spokesman for Amsterdam police said: "A man fell off a hotel boat which was docked in the Sumatrakade.

"We believe he had been sitting and drinking on the deck before he fell.

"We don't know the reason why he fell, although we believe it to have been an accident.

"An investigation has been launched."

He added that blood samples had been taken from the man and would be analysed.

The man, who has not been named, was understood to have been holidaying in Amsterdam and was with a relative when he fell.
