Berlin police say a 20-year-old tourist from Texas drowned after trying to swim across a river in the heart of the German capital.
Police spokeswoman Valeska Jakubowski said the man had jumped into the Spree river early Sunday with a 21-year-old friend.
The older man managed to swim the short distance across the river but the Texan failed to reach the shore.
The latest news from around North Texas.
Two passers-by, including a Danish lifeguard, tried unsuccessfully to save the man. He was recovered by firefighters but later died in hospital.
Jakubowski said Monday the deceased man is believed to have consumed alcohol and drugs before jumping into the river.
She declined to identify the man, citing German privacy rules.
