A man has been arrested on suspicion of arson after a post office was set on fire in Milton Keynes earlier this week.
Thames Valley Police say a man entered the post office on Midsummer Boulevard on Tuesday afternoon (10 June) and made threats to staff.
A short time later, he returned with a petrol can and poured a liquid onto the counter before igniting it and leaving.
The force say the Post Office had a number of members of the public in the building at the time, but, nobody was injured.
Damage was caused to the interior of the business, but the fire was extinguished before it could take hold of other properties.
A 47-year-old man from London has been arrested on suspicion of arson.
Anyone who witnessed the incident is asked to come forward.
