Police said they declared the attack at the mosque was as a terrorist incident with 20 minutes of them receiving a report of a van colliding with pedestrians.
The driver of the van was reportedly subdued by the crowd before being taken into official custody.
A witness told Sky News that two other people fled the scene of the attack, but police said there were no other suspects at present.
British Prime Minister Theresa May called the attack near the north London mosque a "sickening" attempt to destroy liberties that unite Britain, such as freedom of worship.
Many at the mosque, and on social media, criticized the police and the media for what they saw as a too-slow decision to label the mosque attack as terror. "All my thoughts are with those who have been injured, their loved ones, and the emergency services on the scene".

London Mayor Sadiq Khan: The Mayor of London described the incident as a "horrific terrorist attack".
Today's attack his is the fourth terror attack in the United Kingdom in four months, after incidents in Westminster, Manchester and on London Bridge. This is for London Bridge.' And he was smiling, saying: "'Kill me", he said.
"We found a group of people quickly started to collect around the assailant", he said.
His overall impression, he says, was the strong level of support the Muslim community there receives from the local community in times of tension and the "very good relationship" that exist with the local residents.
Khan said there has been a spike in hate crime, including against Muslims, since the recent London bridge attack.
A man intent on killing Muslims plowed a rented van into the group of Londoners - killing one and injuring 10 more - before jumping out and taunting them with slurs, according to witnesses.
But the imam from the mosque outside of which the attack took place came outside and persuaded the angry, grief-stricken crowd to practice peace, not violence.
