Detectives were today hunting for a man whose 83-year-old grandmother was found dead with head injuries.
The body of the pensioner, named in reports as Doris Langlands, was discovered at her home in Green Dragon Lane, Winchmore Hill, north London, on Sunday.
Police issued an appeal to find James Langlands, also known as Jack, who sources said is believed to be the victim's grandson.
The 26-year-old is white, 5ft 11in and clean-shaven, with dark brown hair.
He was last seen in north London wearing a light-coloured "beanie" hat, a three-quarter length beige or light green jacket and a light-coloured pair of trousers.
He was carrying a dark shoulder bag.
A spokesman for the Metropolitan Police said officers were called to Ms Langlands' house at around 7.15pm and she was pronounced dead at the scene.
Her next of kin were informed but police are waiting for her body to be formally identified.
Neighbours paid tribute to the pensioner, describing her as "friendly" and "sweet".
Andrea Hollins, 44, told The Daily Telegraph: "She was a very sweet lady. I think she was married but I haven't seen the old man in some time so perhaps he passed away.
"She lived here for a very long time. She was a very friendly woman who always said 'hello' if you passed her in the street.
"She was always out and about. She was quite small and petite, like a traditional grandmother."
Police warned members of the public not to approach Langlands but to call the incident room at Sutton on 020 8721 4155 or Crimestoppers, anonymously, on 0800 555 111.
