Line of Duty biscuits decorated with lines such as 'Bent Copper' have proved a massive hit from fans - with more being cooked for this weekend

The jam-filled empire biscuits have icing messages such as ‘God give me strength, ‘Hastings like the battle’, and ‘The letter of the law’.

Fans of the cop drama have been stocking up on boxes of biscuits to eat during the TV show.

Staff at The Brooklyn Cafe in Shawlands, Glasgow, have been engrossed in the Martin Compston drama, prompting the idea.

The biscuits cost £2.20 each and sold out on Saturday (April 10), with more made for Sunday's airing of the drama and around 100 sold over the weekend.

General manager Jonny McDonald, 34, decided to get the icing pens out and make it the theme of the week - and is planning a bumper biscuit twice the size of normal ones for the finale.

Dad-of-two Jonny said: "We sold around 100 last weekend.

"We normally sell a lot anyway but this is probably about 50 per cent more than we usually do."

"We always do personalised biscuits, normally for birthdays or special occasions but not often just for TV programs.

"We do different themes each week, we have done random themes covering pretty much any topics.

"The owner, David, was going on about how good Line of Duty was last week so I told him to get it on the biscuits and the rest was a blur.

"We're all engrossed in the show though, so it's been really fun to design, and the response has been massive.

"The last time the biscuits went this crazy was the Tiger King biscuits early last lockdown."

They are planning to make a massive batch for this weekend, then change the theme up again.

The cafe, which has been open since 2000, is planning on bringing them back for the penultimate episode of season 6 on May 9, with a special finale box.

Johnny added: "We are going to do a load for this weekend then change the theme up after that.

"We plan to bring them back for the finale of season 6 on May 9 with a special finale box.

“We will launch the details of the finale box just after the penultimate episode of the season so details will be out on April 25 with a limited edition biscuit twice the size of the normal ones in each box.”
