Abul Koyair, 20, and his injured brother Mohammed Abdulkahar, 23, were released without charge a week after the raid on their Forest Gate home.

Mr Abdulkahar said: "I thought one by one they're going to kill us. At that time I thought I was going to die."

The police earlier said they were acting on "specific intelligence" that a chemical device was in the house.

According to the brothers' lawyer, the unsuccessful police search included digging up plants in the garden and drilling holes in the shower.

Mr Abdulkahar said he "had no idea" who spoke to the police, prompting the raid.

'Seemed like fire'

"From my point of view the person who did this they have terrorised me and my family," he said.

Speaking at a press conference, Mr Abdulkahar said he was in great pain when he was taken to the hospital with a gunshot wound, saying: "It seemed like fire. I was burning."

At one point Mr Abdulkahar broke down in tears as he described the raid, involving 250 police, which he initially thought was a robbery.

He described the moment when he was shot. "We both had eye contact, he shot me straight away," he said.

"I just saw an orange spark and a big bang. I flew into the wall, slipped down. There was blood coming down my chest. I knew I was shot.

I feel fear when the room is dark

Reaction to brothers' claims

"It's ruined my life from the day, from the time they entered my house. It's turned my life upside down."

He alleged he was dragged from the house onto the street where an officer applied pressure to the wound. It was only then Mr Abdulkahar said he realised that police were involved.

He said he had been unable to sleep since the raid.

"I can't go sleep, I keep on having flashbacks, I can't go sleep with the light off. I feel fear when the room is dark."

Mr Koyair also gave his version of what happened during the police raid.

"All of a sudden my brother went down the second sets of stairs and I heard a loud bang, and it was a big flash and then after that everything was so quiet," he said.

"No-one said nothing, I thought it was like a dream at first, no-one was speaking, saying anything.

"After about one, two minutes I realised that this is not a dream. I realised that my own brother got shot for no reason."

Police application

When asked if the Metropolitan Police chief Sir Ian Blair should resign over the raid, Mr Abdulkahar said: "I believe I shouldn't have been shot."

Mr Koyair added: "We feel that whoever is responsible should be put to justice. Sir Ian Blair, whoever gave the order for this to happen."

The brothers, who had been held under the Terrorism Act 2000, were released on 10 June after police found no trace of an alleged chemical device at their home.

But Mr Abdulkahar said suing the police "is not even in our heads at the moment".

He was more interested in getting an apology from the police, he said.

"I want everyone that was involved, whoever gave the order for the raid to happen, for the shot to go off, everyone involved to apologise."

The police have defended the raid and the Independent Police Complaints Commission (IPCC) is investigating.

An official spokesman for Tony Blair said the prime minister remained 101% supportive of the police, saying: "The PM's view has not changed at all."

The director of campaign group Liberty, Shami Chakrabarti, said questions remained about the "appropriateness of [police] action".

She did not want to prejudge any official scrutiny of the raid, but added: "We also have to be concerned about the shot and why that was necessary."
