Gardai in Dublin are looking for two armed men dressed as builders who used a stun gun on a cash delivery guard before stealing a cash box and escaping on foot.
The men approached the cash delivery van on Lower Grand Canal St as it was making a cash delivery just after 10 am.
They immobilised the guard with the stun gun before running off with a cash box which they dropped and was later recovered unopened.
The guard is being treated in hospital.
