United Kingdom police: London attacker acted alone, motive may remain a mystery

Detectives have searched 21 properties in London, the central English city of Birmingham and Wales as they look into the life of killer Khalid Masood, London's top counterterror officer Mark Rowley said, as police released a new photo of the attacker.

British cops have made two more "significant" arrests in connection to the bloody terror attack that rocked London on Wednesday, bringing the total arrest number to nine as the historic capital attempts to return to everyday life.

Details are gradually emerging about Masood, who was shot dead by a police firearms officer after he rammed a vehicle into pedestrians on Westminster Bridge and stabbed an unarmed police officer outside parliament.

Four people were killed and 50 others injured after the assailant rammed a auto into pedestrians and stabbed a police officer outside the British parliament.

The 52-year-old was shot dead by armed officers outside the Palace of Westminster around four minutes later.

There were still two men arrested in Birmingham, aged 27 and 58, and a man and a woman aged 35 and 32 arrested in Manchester, who remained in police custody.

Those arrested on Thursday were: A 39-year-old woman in east London.

Now, the young woman has released a statement to charity Tell MAMA, about the attack and about the fact she was the subject of such disgusting xenophobia.

A 23-year-old man arrested in Birmingham at the same address was released with no further action.

He also named a 75-year-old man who died of his injuries in hospital on Thursday as Leslie Rhodes from Streatham in south London. His most recent conviction was in 2003 for possession of a knife.

Because they had so little information on his recent activities, investigators were now having to do very basic inquiries to build up a picture of his recent background and activities, the source said.

Spanish teacher Aysha Frade and 54-year-old Kurt Cochran from Utah died Wednesday after being hit by the auto, while police officer Keith Palmer was stabbed to death outside the Houses of Commons.

Fifty people were injured in the attack, with 31 receiving hospital treatment. He was arrested in Birmingham by police officers who are also investigating. They were all arrested on suspicion of preparation of terrorist acts and quizzed by police trying to piece together how he came to carry out the attack.

"We are proud that we stand with all of our faiths and communities and I would like to encourage everyone to remain vigilant".
