Ricky Hatton burglary: Thieves stole watches and cash
Watches worth £28,000 and a large number of 500 euro notes were stolen during a burglary at Ricky Hatton's home after he tweeted he was away.
Thieves ransacked the boxer's house in Hyde, Greater Manchester after breaking in between 30 January and 2 February, police said.
He had earlier tweeted he was heading to London for a TV appearance.
A 37-year-old woman has been arrested on suspicion of burglary and released on bail pending further inquiries.
Det Con Marc Baker said: "These were some valuable and quite distinctive timepieces and we hope that this will assist us in tracking these items and the offenders down.
"One was a gold Rolex Yachtmaster worth £20,000, while the other was a stainless steel Rolex Explorer worth £8,000.
"Similarly, the euros were in large denomination notes not typically used by the public."
Hatton, 36, announced his retirement from professional boxing in July 2011, but returned to the ring in November 2012 to fight Vyacheslav Senchenko.
The former two-weight world champion retired again after defeat at the Manchester Arena.
