The suspect in the murder of a police officer in south London is Louis De Zoysa, the BBC has learned.
New Zealand-born Sgt Matiu Ratana, 54, died in hospital after being shot and killed at Croydon Detention Center while a handcuffed suspect was taken into custody on Friday morning.
Mr De Zoysa, 23, from Norbury, who allegedly took his own life, is seriously ill in hospital.
Another man was arrested on suspicion of supplying a firearm.
Officers made the arrest around 2 a.m. BST in Norwich. The man is currently in detention.
Police were unable to speak to the man suspected of shooting Sgt Ratana.
He was initially arrested for an alleged drug offense and for possession of ammunition.
The shots were fired as officers prepared to search the suspect – who was still handcuffed – with a metal detector, according to the watchdog of the Independent Office for Police Conduct (IOPC).
The second arrest came as Sgt Ratana was recalled by friends and teammates at East Grinstead Rugby Club, where he was a head coach.
West Sussex club vice-chairman Matt Marriot said they had to arrange two separate minutes of silence because “the interest has been quite huge”, with “people coming from all over the country”.
He said Sgt Ratana, known as Matt, had been “a role model, a mentor and often a father figure” and that the club mourned him “as a member of the family”.
PC Sarah D’Silva, who plays for the club’s women’s team and works at Croydon Police Station, said she felt ‘extremely poignant’ joining the minute’s silence.
She wore her police uniform to pay tribute to Sgt Ratana, whom she described as “an absolutely fantastic character, full of life, with the biggest smile you have ever seen”.
Police Commissioner met Dame Cressida Dick, speaking earlier at the National Police Memorial in central London, said she “was not at all surprised” by the number of tributes she received. been returned.
“Matt was an amazing person… he had a wonderful personality and he was very good at his job,” she said, adding that he was a “proud Kiwi”.
during a national police memorial service, saying his death was the “last heartbreaking proof of the risks.”
Officers focused on four crime scenes in London and Surrey as part of the investigation, including the house where Mr De Zoysa’s parents live.
Searches continue at Croydon Custody Center, where the shooting took place, an address in Park Road, Banstead, Surrey, and an address in Southbrook Road, Norbury.
The search for another scene in Pollards Hill, where the suspect was originally arrested, has come to an end and the cords have been pulled.
Residents near one of the research areas in Banstead, Surrey said they heard a loud noise on Saturday morning and were later told that a controlled explosion had taken place.
Banstead’s address is down a long driveway and its grounds contain a series of concrete bunkers. A marked police car guards the entrance to the property.
Sgt Ratana was shot in the chest at Croydon Detention Center on Friday.
On Saturday evening, Assistant Deputy Commissioner Stuart Cundy said police had “recovered the weapon from the guard room where Matt was shot.”
“We also have video surveillance of this guard room which shows the events, and we have videos of the bodies of our police officers involved in the circumstances surrounding the arrest of the suspect,” he added.
The murder investigation should focus on the motive for the murder.
The force previously said the shooting was unrelated to terrorism.
It is believed the suspect was known to counterterrorism police and his background could feature prominently in police investigations, BBC home affairs correspondent Danny Shaw said.
The suspect had been referred to the government program Prevent, aimed at preventing people from joining extremist groups and carrying out terrorist activities.
Sgt Ratana arrived in the UK in his early twenties in 1989 and joined the Met Police two years later.
He was originally from the Hawke’s Bay region of New Zealand and was educated at Palmerston North Boys’ High School, north of the capital, Wellington.
The agent, who had a partner and an adult son from a previous relationship, would have been eligible for retirement in two months.
Neil Donohue, who was a friend of the officer and runs a gym he frequented, said Sgt Ratana had gone “in custody” [of policing] simply because he had had enough on the streets and thought it was his safest option, just to get him to retire ”.
