Malcolm Lagg was an outgoing elderly gentleman who worked as a lollipop man outside Bessie Street School. He decided to retire in December 2012 and started looking for a replacement officer to train. Dennis Tanner successfully landed the role. Ashamed to tell wife Rita about his new job, Dennis tried his best to remain unrecognised but he was soon spotted by Steve McDonald who poked fun at him. Angered that Dennis had held him up, Steve drove off with Dennis's lollipop stick and later that day, Malcolm turned up at the Rovers with PC Carson to reclaim the council's property.
