"No pain, no gain” took on a new meaning for the members of a gym in the capital’s Chamkarmon district this week.

While they were inside pumping iron, a thief, 21, was cleaning out their lockers.

Police said the suspect would routinely disguise himself as a workout enthusiast then roam the club looking for loot. The jig was finally up on Tuesday.

After being arrested, the man confessed to stealing money and phones on three occasions. RASMEI KAMPUCHEA
