A wallet that contained items from a man's dead daughter was stolen in Leigh.
Sometime between midnight on Tuesday 4 September 2012 and 6.30am the same day, a home belonging to 52-year-old Mark Shaw on Hallworthy Close was broken into.
The house was searched and a wallet was stolen before they left.
The wallet contained a number of items that reminded the victim of his 12-year-old daughter who sadly died from Cystic Fibrosis nine years ago.
A piece of paper with drawings of animals and a Buddha from his daughter
A nappy pin that had been used on his daughter when she was a baby
A small silver and jade Buddha figurine
And an English penny dated 1919 that had been given to the victim by his Granddad.
Detective Constable Zoe Sajewicz from the Volume Crime Team said: "This is a truly heart breaking crime that has left the family deeply upset.
"These items are of great sentimental value to the victim and he is desperate for their safe return. They are irreplaceable and a constant reminder of his daughter who would have turned 21 this year.
"It is likely the offenders did not realise what was in the wallet and just took it. I am appealing directly to them to search their conscious and do the right thing by returning the wallet.
"Anyone who may have seen the possessions similar to the ones described or a discarded 'Fat Face' wallet, I would urge you to contact police as soon as possible."
Anyone with information should phone police on 0161 856 7249 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
