A man in his 20s has died after suffering knife and gunshot wounds in east London.
The victim was attacked in Church Road, Manor Park, shortly before 9.30pm on Monday night.
More police were sent to the area on Monday night as an investigation began.
A special stop and search order was imposed in Newham, which will remain in place until 1.30pm on Tuesday.
Mayor of Newham Rokhsana Fiaz tweeted: "My deepest condolences to his family today following a devastating incident last night in Manor Park, @NewhamLondon.
"Myself and the Deputy Mayor @grayee, were at the scene last night providing reassurance to local residents and those there who knew the victim."
Irmantas Miniauskas, 31, of nearby Meanley Road, said a team of around six police officers had knocked on his door early on Tuesday morning.
"They were knocking on all the doors to see if we heard anything - I didn't hear anything," he said.
Mr Miniauskas said the area is usually quite safe because it is mostly residential properties.
