Police are hunting a man who stole a grieving father's laptop during his six-year-old son's funeral.
The laptop was being used to show photographs of the boy during the service at a church in Hammersmith and Fulham on November 2.
The boy's 34-year-old father attended the Pentecostal City Church, in Scrubs Lane, NW10 for his son's funeral service.
After the funeral service finished at about 1pm, the mourners left the church to go to Kensal Rise for the burial ceremony.
When they returned to the church they discovered the laptop had been stolen.
The Metropolitan Police released this footage on Tuesday in a bid to catch the suspect, who is described as a black man, aged about 40.
He wore a black hooded jacket, a white hoodie with writing on the front and blue jeans. He also walks with a distinctive limp.
Detective Constable Ben Kirkham from Hammersmith and Fulham CID, said: "The church hall was left open after the congregation left for the burial. We have CCTV that shows a man walk into the building.
"After spending about 15 minutes inside he is then seen removing the laptop from the case and putting it into a carrier bag before leaving.
"The theft of this laptop with the father's precious photos of his son has obviously and understandably caused huge upset for the entire family who are already going through a very difficult time."
The computer taken was a HP laptop serial number 8CG42003G6.
