Festival-goers have defied a ban on flares and smoke devices despite numerous warnings issued by festival bosses and police.

As thousands descend on Glasgow Green for the second day of TRNSMT, many have reported ramped-up security checks at the festival gates after 13 people were arrested yesterday.

But despite tough searches including body pat-downs, some have managed to slip flares and other smoke devices through the doors and into crowds.

Videos show pink smoke let off above fans rocking out to Fontaines DC at the King Tut's stage on Saturday afternoon.

It is the second day warnings have been ignored: we told you yesterday that fans let off the devices during Glasgow singer Gerry Cinnamon's set.

Flares and smoke devices are among the list of prohibited items issued by organisers, and they say CCTV footage will be used to catch those using them.

Superintendent Simon Jeacocke said: “This has been an extremely positive event so far and festival-goers have been in great spirits.

“We’ve arrested 13 people for minor offences since opening on Friday and because of positive police searches at the gates, and on-site partnership working with event organisers, we’ve detected and deterred 17 people from entering the site with drugs.

“Our message is: know what you can and cannot bring on-site. Drugs, smoke devices and flares are illegal and you will be arrested if we find them on your possession.

"Stay safe and don't take the risk.”
