A man was stabbed through the heart at Warburtons’ bakery in Bellshill after a row over tea breaks, a court was told this week.

The High Court in Glasgow heard how Steven McArdle died of a stab wound through the heart during a 12-hour night shift on 8 March. Colleague Paul Steadward, 35, has denied murdering McArdle, claiming instead that he was attacked by McArdle.

The court heard that Steadward and McArdle had rowed over the length of time McArdle was taking for tea breaks at the bakery. The jury was shown CCTV images of both men leaving the factory. Steadward was then filmed going back inside and then leaving minutes later, carrying a bag.

Taxi driver John Hendry said in evidence that he picked up Steadward at 4.30am on 8 March, about a mile from the bakery. Hendry said that during the course of the journey he asked Steadward what his shift had been like and he replied that he had stabbed someone. The trial continues.
