Private investigator Glenn Mulcaire has been arrested today in connection with phone hacking and perverting the course of justice, according to reports.

The private investigator, who lives in Cheam, has previously served time in jail for hacking phones of royal aides on behalf of the News of the World.

Police said that a 41-year-old man had been arrested this morning at an address in London in connection with phone hacking and perverting the course of justice.

They would not confirm the man’s identity.

He was being held in custody at a south London police station, a spokesman said.

The Scotland Yard spokesman said: "On December 7, 2011 officers from Operation Weeting arrested a man in connection with phone hacking and perverting the course of justice.

"At 7am officers arrested the man at an address in London on suspicion of conspiring to intercept voicemail messages, contrary to Section 1 (1) of the Criminal Law Act 1977 and on suspicion of perverting the course of justice contrary to common law. The man is currently in custody at a south London police station.

"It would be inappropriate to discuss any further details at this time."
