A Swedish housing developer has offered a cash reward for any tips leading to the return of statues depicting two officers missing from outside a former police station in Malmo.

The two bronze statues, named "Vaktaren" (The Guardian) and "Poliskonstapeln" (The Police Constable), have guarded the gate of the building in the city since it was constructed in 1934.

Developer Riksbyggen is converting the station into apartments, but said the statues were an important part of the building's history.

"We want to maintain the history and retain as much of the heritage that exists," project manager Emil Nilsson said.

The officers have been missing for a few months and with no leads Riksbyggen is offering a reward of 10,000 Swedish kronor (€960) to anyone with information leading to the "unharmed" return of the police officers.

Riksbyggen said "Vaktaren" was last seen wearing an overcoat, a cap and clogs, while "Poliskonstapeln" wore the 1926 standard police uniform with a striped coat and boots "at the time of the disappearance."
