Two men still remain in police custody over the Westminster terror attack

They have named 52-year-old Briton Khalid Masood as the man who killed four people in Westminster on Wednesday, but issued a fresh plea for any information that might explain why he did it.

The person - who in this case is Masood - is not representative of the British Muslim population.

Police raided a home in Birmingham where Masood lived until late previous year, according to a neighbour, Iwona Romek, who said he was also married and a father.

The revelation came as Met detectives continued to investigate whether Masood, who used a number of other aliases, acted alone or had accomplices.

"Whilst there is still no evidence of further threats, you'll understand our determination is to find out if either he acted totally alone, inspired perhaps by terrorist propaganda, or if others have encouraged, supported or directed him", said Rowley.

Detailed police analysis reveals that Masood's attack started last Wednesday at (GMT) 14:40:08 on the Westminster Bridge, when he drove his marauding vehicle on the pavement full of people, killing three people and leaving many injured, some critically.

Two officers remain in hospital with "very significant" injuries, one of whom has been identified as PC Kristofer Aves.

Two were still in a critical condition and one was being treated for life-threatening injuries, police said on Friday.

Prime Minister Theresa May said Thursday that Masood was "investigated in relation to concerns about violent extremism" some years ago.

"It is still our belief, which continues to be borne out by our investigation, that this attacker acted alone and was inspired by worldwide terrorism", the police said.

A 32-year-old woman, who was arrested in Manchester, was released on bail until late March.

The manager of a hotel where Masood stayed the night before he plowed his 4x4 into pedestrians on Westminster Bridge and then stabbed a police officer at Parliament said Friday that he seemed unusually outgoing and mentioned details about his family, including having a sick father.

"Masood was not the subject of any current investigations and there was no prior intelligence about his intent to mount a terrorist attack", the police said in a statement.

Thousands of people gathered in central London Thursday night, just a few minutes from the scene of the attack at the British Parliament, for a vigil to commemorate the victims.

"As a result of their co-operation and our enquiries, we are completely satisfied that they are not connected in any way to the terrorist attack in Westminster on Wednesday", he said.

"He was a peripheral figure".

A tribute to the victims of the attack left at Scotland Yard.

Khalid Masood's attack began at 2.40pm on Wednesday, and was over by 2.41pm, according to a detailed investigation by the Metropolitan Police's Counter Terrorism Command. Later, police shot the attacker dead.
