“requested him to communicate the fact..”

There’s an interesting detail from this report on the Brendan McFarlane trial which failed to make it into subsequent reports

Cross-examined by defence counsel Mr Hugh Hartnett SC, the superintendent said he had no knowledge that Mo Mowlam was due to sign [McFarlane’s] final release papers at 3pm that afternoon but he said that McFarlane informed him of this and requested him to communicate the fact that he has been arrested to the Northern Ireland Office, which he did.
