While his wife Shakila, 45, and son Farhad, 24, fled the blaze, but Saber's family say he stayed behind because he was injured.

The 57-year-old was last heard from at 2.20am when he made a frantic phone call to a relative to say that the building was burning and that there was "no help".

Saber, whose birth name is Mohamed, is understood to have parted with Shakila and university graduate Farhad at 3.30am but hasn't been seen since.

The father-of-one's nephew Reshad Habib, who lives in the Netherlands, said: "We are all trying to find him.

"He was last heard from at 3.30am when he told his wife and son to leave him. He said that they had to get out.

"He said they should go and he would follow.

"We all don't know the exact reason why he waited behind, but we think he was injured or something.

"They were both taken to hospital. We don't know how they are.

"We haven't heard anything from my uncle since.

"They had been living for 20 years in that flat and they lived on the very top floor of the building.

"We got a call when the fire started. He said there was a big fire at the flat and that there was no help at the moment. That was at 2.20am.
