Two women who are feared to have been killed in the Grenfell Tower fire were allegedly threatened with legal action after campaigning for better fire safety.
Nadia Choucair and Mariem Elgwahry were both sent letters asking them to stop their campaign, according to reports.
The Mirror said they were fighting alongside the Radical Housing Network against the Kensington and Chelsea Tenant Management Organisation.
The pair are also believed to have conducted a protest outside the offices of the organisation as well as create a petition, The Independent said.
Pilgrim Tucker, who is part of the Radical Housing Network, said: “They both just wanted to do their best for their neighbours and keep everyone safe.
"Things had got so bad they knew a disaster like this was inevitable, but if there was a chance of stopping it they were up for the fight.
"We have to get justice for them. The TMO treated tenants disgracefully and with disdain.
“They bullied them and persecuted those like Nadia and Mariem who were brave enough to speak out, branding them troublemakers."
The Kensington and Chelsea Tenant Management Organisation says it cannot comment on the alleged threat and is cooperating with current investigations.
