COPS in a Mexican city are so fat officials are considering paying them a bonus to slim down.

The central Mexican city of Aguascalientes will decide next week whether to pay £5 for every kilogram that officers lose, a police spokesman said.

"We do have some fat officers. We have been encouraging them for a while to lose weight, to be more agile, to do sport," he added.

Obesity is one of the biggest health problems in Mexico, where diabetes is the biggest killer.
