Police investigating the Grenfell Tower fire say they have carried out 13 interviews under caution.
The Metropolitan Police would not confirm the number of people who had been interviewed but said more interviews were scheduled.
It added more than 7,100 statements had been taken from “witnesses, community and family members, emergency services personnel” and “other sources”.
The fire, which destroyed the London block on 14 June 2017, left 72 dead.
Karim Mussilhy, whose uncle was killed in the fire, said the interviews showed “some positive steps” were being taken.
Mr Mussilhy, who is vice chairman of the campaign group Grenfell United, added that “it would be interesting to find out” who had been interviewed.
Labour MP for Kensington, Emma Dent Coad, said it was “just what our community wanted to hear”.
Three interviews had been conducted under caution when police announced a “new phase” of their investigation in July last year.
However, police have said it could be the end of 2021 before criminal charges are considered.
The Met has said it wants to see the conclusions of the public inquiry’s second phase, which starts next year, before compiling a file of evidence for the Crown Prosecution Service to look at.
Phase two will examine causes of the fire, including the use of cladding blamed for helping it to spread.
In 2017, police said they had “reasonable grounds” to suspect that corporate manslaughter offences had been committed.
Love Island star Mike Thalassitis left a notebook with messages to his family at the scene of his death, an inquest has heard.
The 26-year-old reality star and former footballer was found hanging in a park in Edmonton, north London, on 16 March.
His death sparked calls for improved aftercare for people who take part in reality TV shows.
North London Coroner’s Court concluded on Wednesday his cause of death was suicide.
Senior coroner Andrew Walker said Mr Thalassitis left messages “which clearly set out his intention that his life should come to an end”.
Former Love Island contestant Montana Brown said Mr Thalassitis had been in a “dark place” in the months before his death.
Toxicology results showed there was cocaine, ethanol and paracetamol in his system at the time of his death.
Love Island said it would be offering further support and “bespoke training” to contestants in future.
With a career in lower league football, Mr Thalassitis joined the cast for Love Island in 2017. He was also filmed for Celebs Go Dating.
Producers of the ITV2 show paid tribute to him at the end of the opening episode of the new series, which aired on Monday night.
Beneath a photo, a message on screen read: “In loving memory of Mike Thalassitis 1993-2019.”
Last year, a contestant on the 2016 series of the show, Sophie Gradon, died aged 32. An inquest into her death found she took cocaine and alcohol before killing herself.
