The alleged Finsbury Park attacker told police he was "flying solo" after ramming a van into Muslim worshippers, a court has heard.
Woolwich Crown Court is hearing evidence on whether Darren Osborne may have acted with accomplices, namely two men known as Dave and Terry Jones, and who was driving the van.
Police told the jury CCTV shows only Mr Osborne inside the van and body camera footage taken shortly after his arrest shows him telling an officer that he was driving.
In an urgent safety interview conducted later in hospital, he allegedly told a counter-terrorism there was no one else involved, adding: "I'm flying solo, mate."
The father-of-four denies charges of murder and attempted murder after allegedly ramming a van into Muslim worshippers shortly after midnight on 19 June.

Prosecutor Jonathan Rees QC yesterday presented CCTV showing the movements of Mr Osborne driving around the area in the minutes before the attack.
Deemed by prosecutors to be an act of terrorism, it killed one man and seriously injured nine others, including a victim who was left trapped under the van.
Mr Rees said the new evidence was “directed at the issue of whether Mr Osborne, the defendant, acted together with other persons, specifically a man called Dave and a man called Terry Jones”.
The jury was played a series of CCTV footage clips showing the van used in the attack driving around Finsbury Park in the 10 minutes before the attack.
At one point it is seen parked while Mr Osborne, 48, buys a drink and returns, and there is a four-second gap in the coverage between cameras shortly afterwards.
Another clip shows the view of the attack from the other side of a fence that formed a dead end.
“One of the issues being considered is how many people got out of the van after the incident occurs,” Mr Rees said.
The van is seen crashing into bollards, with a single figure getting out of the driver’s door, stumbling and running off camera pursued by three people.
DC Hazel Londt, of the Metropolitan Police, told the court she had reviewed footage for eight hours and did not see anyone else inside the van.
Asked whether there was any evidence of anyone apart from Mr Osborne entering or leaving the vehicle, she replied: “No.”
Survivors of the attack previously told the court they saw only one person in the van and apprehended Mr Osborne after he allegedly attempted to flee, pinning him to the ground before police arrived.
“I’ve done my job, you can kill me now,” he allegedly told them, while smiling.
Experts concluded the van had been “intentionally steered” into a group of Muslims who had left Ramadan prayers at two nearby mosques.
They were clustered around 51-year-old Makram Ali, who had collapsed, and were waiting for an ambulance when the van struck.
A pathologist told the jury Mr Ali had not suffered a heart attack and died of “catastrophic” injuries caused by being run over.
The prosecution alleges that Mr Osborne deliberately targeted Muslims after becoming “brainwashed” in the wake of watching a television drama on the Rotherham grooming scandal and reading far-right posts.
The defendant allegedly drove from his home in Cardiff to target a pro-Palestinian march in London on 18 June but found surrounding roads closed by police and started searching for mosques in London.
Bar staff from a pub where Mr Osborne drank on the night before the attack told them he ranted about Muslims, grooming gangs, the Labour party and other topics before being told to leave.
Similar themes were addressed in a handwritten note found inside the van, which also hit out at figures including singer Lily Allen, Jeremy Corbyn and Sadiq Khan, the mayor of London.
The trial continues.
