Body of eighth London Bridge victim found in River Thames

Detectives searching for a Frenchman who disappeared during the London Bridge terror attack have recovered a body from the River Thames.

Specialist officers from the Marine Police Unit recovered the man's body on Tuesday evening near Limehouse, about three miles from the scene of the atrocity.

He has not been formally identified, but Xavier Thomas' next of kin have been told about the development.

Mr Thomas, 45, was caught up in the attack with his girlfriend Christine Delcros.

The couple, who were visiting London for the weekend, were walking south across London Bridge when the attack happened.

Ms Delcros, who is also French, was seriously injured when she was struck by the van used in the attack.

Meanwhile, the family of Spanish banker Ignacio Echeverria have confirmed he was killed in the attack after trying to fend off a terrorist with his skateboard.

According to Spanish media, relatives were told of the 39-year-old's death by Spanish ambassador Carlos Bastarreche, after his family flew to London.

Mr Echeverria was reported missing after he was last seen in Borough Market defending a woman.

Isabel Duran, a relative, wrote on Twitter: "Ignacio Echeverria attacked the terrorists to try to save a woman.

"He is in heaven with his inseparable skateboard."

In the latest development in the police investigation, a 30-year-old man was detained in Ilford, east London, on suspicion of the commission, preparation or instigation of terrorist acts.

The arrest followed a raid at a property that is still being searched. A total of 15 people have been arrested in the UK as part of the investigation, with 12 released without charge.

The three men behind Saturday night's attack, in which eight people died and 48 were injured, were Youssef Zaghba, 22, an Italian national of Moroccan descent who was living in east London, Pakistan-born British citizen Khuram Shazad Butt, 27, and Rachid Redouane, 30, who claimed to be Moroccan-Libyan.

Australian nurse Kirsty Boden, 28, Canadian national Christine Archibald, James McMullan, who lived in Hackney, east London, Australian nanny Sara Zelanak, 21, and French waiter Alexandre Pigeard, 27, were among those who died in the atrocity.

French media have also named Sebastien Belanger, 36, as one of the victims.

Ten people remain in a critical condition in hospital.

Mayor of London Sadiq Khan said there had been a spike in "racist incidents" following the attack and has warned that police will take a "zero-tolerance approach to hate crime".

As details of the victims and the heroes who stepped in to help the injured continue to emerge, concerns have been raised that extremists could use Ireland as a gateway for further acts of terrorism in the UK.

A senior Islamic cleric has told Sky News he suspects that Redouane entered the UK by crossing the Irish land border.

Police in Ireland arrested one man in Limerick on Monday night and a second in Wexford 24 hours later.

It has emerged that Zaghba was placed on a watch list by Italian authorities and flagged to British intelligence agencies after he was stopped from flying to Turkey amid suspicion he was trying to get to Syria.

A lack of evidence on his intentions meant his phone and passport were returned, according to Italian media. Scotland Yard has said Zaghba was not a police or MI5 "subject of interest".

Butt, who worked on the London Underground for nearly six months, was investigated by officers in 2015 but was "prioritised in the lower echelons of our investigative work" when no evidence he was planning an attack was found.

Perpetrators of all three terrorist attacks in the UK this year - two in London and one in Manchester - have at some point been monitored by security agencies.
