Teen left man permanently scarred in Sauchiehall Street knife attack

Landon Deehan, 19, struck David McSherry on the face with a knife on Glasgow's Sauchiehall Street on June 24 2026.

Glasgow Sheriff Court heard that Deehan initially breached a bail condition by being outside of his home between 8pm and 7am.

Deehan spoke to a James Atkinson at 10pm outside of Tesco and tried to get him to shake his hand.

Mr Atkinson repeatedly refused to do so before eventually complying with Deehan.

Mr McSherry then appeared and gestured for Deehan to go away.

Prosecutor Abbas Ali said: "Deehan reached into his waistband and removed a large knife.

"He struck Mr McSherry to the face with the knife.

"Deehan was wearing a black face covering throughout."

Mr McSherry took refuge in the Tesco where staff offered assistance before he was sent to hospital.

He was found to have suffered a wound to the front left side of his head which required 14 stitches to close.

Mr Ali added: "Mr McSherry will be left permanently scarred."

The incident was caught on CCTV and Deehan was identified.

The attacker later handed himself into police.

Deehan pleaded guilty today to the assault to Mr McSherry's severe injury and permanent disfigurement.

He also admitted having a knife in a public place without a reasonable excuse and breaching his bail conditions.

Sentence was deferred pending background reports until next month by Sheriff Louise Arrol KC.

Deehan, who appeared from custody, had his remand continued meantime.
