Police in Croydon are looking for a couple after officers discovered holiday photos of them on a stolen memory card.
The photos were discovered after officers arrested a 53-year-old man on September 9.
The man, who police describe as one of Croydon's top five prolific burglars for going equipped to steal and handling stolen goods, was bailed to return to a south London police station in November.
In his possession was a memory card containing lots of photos of a couple and two girls believed to be their daughters aged between two and four, on a holiday in Egypt.
DC John Davis, from Croydon Serious Acquisitive Crimes Unit said: "We have arrested a prolific burglar in the Croydon area who was in possession of property believed to be stolen and we are keen to identify the victims and unite them with their family photos.
"This will also assist us in proving further offences and ensuring the suspect is prosecuted."
