A mafia boss wanted in Italy since the 1990s has been arrested in London but may be released because of "significant deficiencies" with his arrest warrant.

Domenico Rancadore, 64, was wanted over his links with Cosa Nostra.

He was the head of a crime family involved in extortion, racketeering and drug trafficking, Italian police said.

But the judge at Westminster Magistrates' Court said there were concerns over the warrant's validity. He will be in court again on Friday.
