Officials in Belgium have opened an amnesty for people to hand back money from a robbery that went wrong.

€1m went flying on the streets of the quiet town of Zedelgem two weeks ago, after thieves threw a safe from their car during a police chase.

Dozens of people were seen sweeping up the cash - and now they're being threatened with two years in jail if they don't hand it back.

The town's mayor Patrick Arnou has said that although authorities have already secured nearly half of the million from the safe, the rest is still out there. And he has described those who keep the money as "beyond decency".

The local prosecutor Jean-Marie Berkvens has warned that ''fraudulent concealment carries a maximum jail penalty of two years."
