A woman was robbed as she tended her sister's grave, police said.
The 65-year-old victim, who has not been named, was left "shaken and shocked", after the incident.
Cleveland Police say she was tending the grave of her sister at St Mary's Church in Norton, Stockton, at about 1330 BST on Monday.
She was approached from behind by a man who knocked her to the ground and stole her bag containing cash and valuables.
A spokesman for Cleveland police said the woman was not seriously hurt in the incident.
He added: "We are looking for a man aged between 18 to 20 years, who was wearing a green jumper which possibly had a hood.
"He made off through the graveyard with the woman's bag and into the street.
"This was a despicable and cowardly act."
