British boxer Dereck Chisora has been detained after a fight with boxer David Haye in Munich.

The fight started at a press conference that followed Chisora's defeat by unanimous decision to Vitali Klitschko.

Chisora joked about Haye losing the WBA belt to Klitschko's younger brother last july, and he and Haye got into a heated exchange.

Haye appeared to have thrown the first punch.

He later picked up a camera tripod and used it during the fight.

Chisora and his coach Don Charles were detained at munich airport today and taken in for questioning.

Klitschko's younger brother told journalists he was surprised and disappointed at what happened.
