The scent of oranges is being used in an experiment to create a calm atmosphere at Rotterdam’s main police station, reports news agency ANP.

The tests, begun in January, aim to establish if workers find the atmosphere improved and prisoners are less aggressive, ANP reports the force’s in-house magazine as saying.
Initial results show the orange scent is having a calming affect in the cells and that demand for sedatives is down, ANP says. The experiment is now being extended for a further six months.
