Officers raided a house in north-west London on Thursday
Three women have been arrested in connection with last week’s anti-terror operation in London in which a woman was shot by police.
The women, two aged 18 and one 19, were arrested on Monday on suspicion of the commission, preparation and instigation of terrorist acts.
It follows a counter-terror operation on Thursday in which a 21-year-old woman was shot at a house in Willesden.
The three arrested women are in custody outside London, police said.
They were arrested after counter-terrorism officers from the Metropolitan Police Force carried out warrants at three addresses in east London.
The Met said the arrests were made as part of an ongoing intelligence-led operation in connection with an address on Harlesden Road.
The 21-year-old who was shot during the police raid on Thursday was discharged from hospital on Sunday before being arrested on suspicion of the commission, preparation and instigation of terrorist acts.
A further six people were also arrested in connection with the incident, including five at or near the Willesden address and one in Kent.
Met Police Deputy Assistant Commissioner Neil Basu confirmed after Thursday’s raid that an active terror plot had been foiled.
Mohamed Amoudi was arrested on Thursday in Willesden, north London
One of those arrested at the address was 21-year-old Mohamed Amoudi.
It was revealed on Saturday that he had previously been quizzed by British authorities under suspicion of trying to travel to Syria to join so-called Islamic State.
The other people taken into custody alongside Mr Amoudi were a 20-year-old woman, a 16-year-old boy, and a man and woman both aged 28.
Another woman, aged 43, was arrested from a property in Kent.
Terror suspects can be held for a maximum of 14 days, with judicial approval.
On Saturday Met Police were given court authorisation to detain the suspects at a south London police station until after the bank holiday weekend.
