UK police have issued an unusual call to help track down a witness to a serious assault - a man wearing a "distinctive" penis costume.
The man was part of a group of around 10 men who may have witnessed the attack in Leeds' city centre on April 2.
The call went out to track him down on Tuesday (local time).
A 26-year-old man was brutally attacked on the street and suffered a shattered shin bone, dislocated and cracked knee, and torn ligaments.
Police hope someone will remember the odd costume and help find the witness.
"While the nature of costume worn by one of the group might be amusing to some, we are hoping that mentioning it will jog someone's memory and assist in tracing those responsible for what was a serious assault that has left the victim with long-term consequences," Detective Constable Gaynor Burt said.
The attacker was a white man around 180cm tall, with a shaved head and wearing a beige or white top.
Police said the group of men who saw the assault may have been there as part of a stag party.
"The costume worn by one of the group is very distinctive and we think anyone who encountered them during the evening would recall it," Const Burt said.
Anyone with information is urged to contact local police.
