Neighbours of Darren Osborne, the Cardiff man arrested after the attack early Monday, said he was a heavy drinker who had become increasingly deranged after Islamist extremists used a vehicle and knives in a murderous rampage in London this month.
The father of four was apprehended by the crowd and is now held on suspicion of murder and terror offenses.
Police searched Osborne's suburban terraced home in Glyn Rhosyn, Pentwyn, yesterday night, as they investigate an act they are treating as terrorism and "clearly an attack on Muslims".
One person was killed and eight injured after a van drove into a crowd of worshippers near the Finsbury Park Mosque in north London last night.
Nine people were hospitalized after the attack and one person has since been discharged.
The van driver, a 46 year old man, was reportedly grabbed by several civilians before the police could reach the scene.
"Your elders could be killed, your sisters could be attacked". Eleven people were taken to hospital.
"Many of the victims are believed to have just left evening prayers at the Muslim Welfare House after breaking the Ramadan fast", says the BBC.
Osborne's sister said she is "very sorry for what's happened". "Those who try to divide us and who aim to spread fear, hatred and division will not succeed".
Mohammed Kozbar, chairman of the Finsbury Park Mosque urged people attending prayers to remain vigilant.
"I could smell alcohol on him and he was grunting and groaning", Gardiner said.
Rowling, for her part, pointed to heated rhetoric by Daily Mail columnist Katie Hopkins, as the Harry Potter author tweeted "let's talk about how the #FinsburyPark terrorist was radicalised".

Londoners bearing flowers and messages of solidarity gathered Monday at the site where Osborne ploughed the van he was driving into pedestrians.
To suggest the attack in Finsbury Park is an act of violence carried out by a "crazed individual" is not only disingenuous, it is risky because it seeks to deliberately erase and deny the fact that hundreds of racist and Islamophobic hate crimes are being recorded in the U.K. It is feared many more are going unreported because Muslims are too scared to report the crimes or do not trust the authorities. Osborne is reported to have said "I did my bit" after bystanders tackled him to the ground.
The tragedy comes during the Muslim holy month of Ramadan and follows three terror incidents in Britain in as many months.
This new kind of terror is an ominous sign for Britain, where the government has proven itself unable to prevent terror attacks after it emerged that the perpetrators involved in the attacks on the concert in Manchester and the London Bridge were already known to British police.
