The daily tabloid said the 44-year-old coach left the club's player of the year awards after a call from his wife, Tami, that their pet Yorkshire terrier was being taken away.

On arriving at his home in the upmarket Belgravia area of London, he saw an official and two police officers who wanted to put the dog in quarantine, fearing it had been taken abroad without jabs, it added.

A spokesman for London's Metropolitan Police confirmed that officers went to an address in central London at 7:45 pm (1845 GMT) Tuesday with an officer from the Animal Health and Welfare Service.

"A 44-year-old man was arrested on suspicion of obstructing police and was taken to a west London police station," he said.

"He subsequently received a caution for obstructing police."

The dog was to have been seized for alleged offences under the Animal Health Act of 1981 and the Rabies Order Act of 1974, he added.

Officers discussed the removal of the animal from the address with the owners. The Sun said Mourinho arrived at his home at 9:00 pm and that he bundled the dog away from police.

A search for the dog was under way, it added.

Mourinho's Chelsea lost their Premiership title to Manchester United this season and take on the Old Trafford side in this Saturday's FA Cup final at Wembley Stadium.
