The man in question, 47-year-old Darren Osbourne, is a father of four.

He was arrested after police arrived at the spot post the incident.

Speaking about the attack, the suspect's family said in a statement, "We are massively in shock, it's unbelievable. It still hasn't really sunk in," while adding, "Our hearts go out to those who've been injured."

Meanwhile Met Police chief Cressida Dick said that the attack was clearly on Muslims and the community will now receive more protection from the police.

Dick also took part in a vigil on Monday night.

Security Minister Ben Wallace told the media that Osbourne wasn't known to security services and possibly acted on his own.

The attack killed at least one person and left 10 others injured.

In the wake of the attack, a Whatsapp group who goes by the name 'War news/Ummah news', urged Muslims to wage a war against their Christian and Jew counterparts.

According to terror analyst Michael S Smith, a message circulated by a 225-member Whatsapp group called 'War news/Ummah news' read, "Oh Muslimeen when your brothers took revenge on the crusader nationals for the slaughter they are carrying out on the Muslims, they were shot on site by the the British Police."

The group was referring to the recent London attacks which accounted for at least 29 lives, apart from injuring dozens.

Questioning the Police's role, where the officers shot all three attackers in the recent London Bridge attack, the group said, "Then how come the Police never shot a Kaafir (atheist)," the message read.

Urging Muslims men to join the jihad, the message read, "Oh Muslims you need to wake up the war is starting now in your own streets outside your own Masajids (mosques). Your elders could be killed, your sisters could be attacked."
