The family of a man shot dead in front of his wife and child on Christmas Eve have spoken of their heartbreak.
Flamur Beqiri, 36, a Swedish national, was killed in Battersea Church Road, south-west London, in what police say could have been a "targeted attack", yards from his home.
In a statement, his family said they were in "shock and grieving" and asked for their privacy to be respected.
No arrests have been made and police continue to appeal for witnesses.
Mr Beqiri's family added: "We thank everyone for their kind thoughts and condolences.
"To have so much sadness at this time of the year is heartbreaking.
"We would kindly ask that you respect our privacy and let us grieve in peace."
Det Insp Jamie Stevenson said: "Flamur's family, his wife and very young child, bore witness to this horrific attack and are coming to terms with having their world turned upside down."
He said Mr Beqiri was of Albanian heritage and had been living in London for four or five years.
"We believe Flamur may possibly have been involved in some criminality in Sweden, and are in liaison with our Swedish counterparts to try to understand what, if any, incidents there may have been that might have led to someone seeking retribution against Flamur in the UK," he added.
The lone assailant is believed to have fled on foot in the direction of Battersea Bridge Road.
The crime scene on Battersea Church Road has now been scaled down and it is expected to be closed soon, the Met said.
According to reports, Mr Beqiri is the brother of former Real Housewives Of Cheshire star Misse Beqiri.
There have been more than 145 homicides in London in 2019, the highest number in a calendar year since 2008.
