He then left in a vehicle that was waiting outside.

No staff member required medical treatment following the incident.

A man in his 30s and a woman in her 50s were arrested shortly afterwards.

They have been taken to two Dublin garda stations where they are being held.

Gardaí say investigations are ongoing.
