A KITCHEN porter took umbrage to being sacked and attacked a manager with a knife during a staff night in, court heard.

John Mallon, 27, lashed out at Christopher O’Connor at Bavaria Brauhaus on September 24 during an argument.

After he was locked out, Mallon went to a nearby Tesco Express where police found him with the knife in his waistband.

He pleaded guilty at Glasgow Sheriff Court to assaulting Mr O’Connor to his injury at the Bothwell Street restaurant, and being in possession of a knife at Tesco on Hope Street in Glasgow City Centre.

The court heard around 6.30am after a staff lock-in at the eatery, Mallon got in to an argument with Mr O’Connor.

Mallon had another argument with Mr O’Connor at the doorway and “lashed out with punches towards his head.”

Mr O’Connor kicked out at Mallon in a bid to put distance between them.

Mallon then removed the knife from his waistband and swung his arm back in a “stabbing motion” towards Mr O’Connor.

The court heard this caused a small cut to his inner arm and he then closed the door on Mallon, who left and went towards Hope Street.

A member of the public who was passing contacted the police and Mallon was found at Tesco, nearby.

Sheriff Alan MacKenzie deferred sentence until a later date and remanded Mallon in custody.
