6. SOUNDBITE (English) Katy Stewart, local resident:
"When I looked outside there was a plain large white van in the middle of the street with the doors open. I also instantly saw a lot of police officers, some of them were in protective clothing and helmets, others were in plain clothes, some of them were putting disposable suits on. They'd entered the property, which was the property where the man was arrested from today and then all we heard was what we thought was gunfire, which turned out to be Taser (stun gun). We saw the kind of deflecting light from that. At some point we also hear the name 'Hassan' shouted twice."

13. SOUNDBITE: (English) Samuel Yates, local resident:
"I'm just absolutely stunned. I was on my way home from work, seen all the police, wondered what was going on, and then to find out there actually was a suicide bomber living two minutes away from my parents, I've probably walked past him, seen him so many times. It's just unbelievable."
14. SOUNDBITE: (English) Mohammed Khan, local resident:
"Four people has been caught, well actually who killed themselves in London, killed 52, they were told they were just going to go straight to paradise. They're not, there's just no punishment for them, but they're just straight to... (Q: Where do you think they will go?) Hell."

Police stormed a house before dawn on Wednesday and fired a stun gun to subdue a man that a witness and media reports said was Somali-born Yasin Hassan Omar, one of four men believed to have carried out the failed July 21 bomb attacks in London.
Members of the bomb squad, some wearing armour, could be seen moving into the building after police evacuated 100 nearby houses in the quiet, ethnically mixed neighbourhood in Britain's second largest city.
The BBC and Sky News reported that the arrested man is suspected bomber Yasin Hassan Omar, however police would not comment on the reports.
Three men were also arrested in pre-dawn raids at another house about 3.5 kilometres (2 miles) away.
The raids were carried out by 50 officers from London's Metropolitan Police Anti-Terrorist Branch and West Midlands Police. No shots were fired.
A police spokesman, speaking on customary condition of anonymity, said the man was being brought to the high-security Paddington Green police station in central London, while the other three were being held in custody in Birmingham, about 190 kilometres (120 miles) northwest of London.
The police spokesman said the operations were in connection with the incidents in London on July 21.
Four bombs were planted on London Underground trains and a bus on that day, but they failed to fully detonate.
Police have since launched a manhunt after releasing images of four men thought responsible for planting the devices.
Police have been trying to determine whether last week's failed bombings were connected to the deadly July 7 attacks that killed 52 people and the four suicide bombers who carried them out.
The Birmingham arrests would bring the number of people that police have said are being held in connection with the July 21 attacks to nine.
Residents living close to the scene of the raids said they were shocked that a bombing suspect had been living in their midst.
