London police said on Monday they had arrested a 22-year-old man after a seven-year-old girl was left fighting for her life following a shooting as mourners left a church service.
Gunshots rang out at the church in Euston, central London, on Saturday afternoon as mourners were leaving a requiem mass for a mother and daughter.
"Detectives investigating the shooting outside a church in Euston have arrested a 22-year-old man on suspicion of attempted murder," Metropolitan Police said.
The man was arrested in Barnet, north of London, shortly before 4:00 pm (1600 GMT) on Sunday and remains in custody, the Met added.
Police believe the shots were fired from a moving vehicle which was then driven away from the scene.
The priest who conducted the service, Father Jeremy Trood, told the PA news agency it had been a requiem mass for Sara Sanchez, 20, and her mother, who both died within a month of each other in November.
The younger woman had succumbed to leukaemia while her mother died after suffering a blood clot on arrival at Heathrow from Colombia, the MyLondon news website reported.
"I heard this almighty bang and I thought this was not normal, and the next minute everyone was screaming and shouting," a neighbour told PA.
In addition to the seven-year-old girl, four women and another girl, 12, were wounded in the incident near the busy Euston train station.
The 12-year-old girl was discharged from hospital after treatment for minor leg injuries.
A 21-year-old woman is also in a central London hospital. Police said her injuries were not life-threatening.
Three other women aged 41, 48 and 54 remained in hospital with non-life-threatening injuries, although the 48-year-old's were "potentially life changing", police said.
A witness told MyLondon the shots were fired as mourners who had attended the mass watched doves being released afterwards.
