The increase was reflected in both the domestic and foreign terrorism categories, with domestic-related arrests rising from 10 to 52.
The number of arrests, the most in a year since data collection began in 2001, mean suspects were being detained at a rate of more than one a day.
British police made a record 379 arrests for terrorism-related offences past year, official figures show.
And there was one arrest following another attack in June, when a van was driven into worshippers near a mosque in north London, killing one man.
The number of terrorists in British prisons has also risen over the past year - by 35 per cent to 204.More news: 7-yr-old's killing: Top school officials held

It also includes the 12 arrests made in relation to March's Westminster Bridge attack and the 23 which came after the attack on Manchester Arena.
In its quarterly bulletin on police use of counter-terrorism powers, the Home Office said 123 of those arrested were charged, of which 105 were taken in on terrorism offences.
However, while the number of arrests soared to a record high, the majority did not lead to prosecutions.
189 were released on bail. He explained: "That's why we're looking at such a high number, but they are still pretty significant".
"It has been an exceptional year in terms of the way in which the police operations and intelligence services have been gathering intelligence and trying to bring people to justice after three terrorist attacks in quick succession". In the next 17 weeks, however, there were the four attacks in Manchester and London, while authorities thwarted six others.
Of this number, 185 people - 91% - of them held Islamist extremist views, and ten others (5%) held far-right views.
