Terror-related arrests have surged by 68 per cent to a new record high as security services confront an unprecedented threat, new figures reveal.
There were 379 arrests for terrorism-related offences in Great Britain in the year ending June 017, a rate of more than one a day and the highest number in a year since data collection began in 2001.
The tally includes dozens of individuals held in swoops in the wake of attacks in London and Manchester which contributed to domestic terror arrests increasing five-fold in the year - writes telegraph.co.uk.

There were 125 detentions under the Terrorism Act last year, an increase of 90 on the total for the previous year.

Of the 125 detentions, 45 led to someone being charged while the others were released.
Of the 379 other arrests 32 per cent resulted in someone being charged while half of those were released without any further action being taken.
A number of others remain on bail.

“Police and security services are working incredibly hard and I think these figures reflect both the threat and the efforts that the police and security services are putting into dealing with them.”
