Two men who robbed a van driver with an axe outside a supermarket in Northampton this morning could be covered in blue dye, police have said.
Northamptonshire Police have now confirmed they were called to a robbery in Blackthorn Bridge Court, at about 11.30am today, outside the Londis and Post Office.
A force spokesman has confirmed two men carried out the armed robbery using an axe and fled with a “substantial amount of money” from a delivery driver.
A money box was later recovered in Maidencastle, which is around the corner and also in Blackthorn.
Officers say the box was fitted with an exploding dye pack, with may have left the robbers covered in blue dye.
They are believed to have fled on a red or orange motorcycle.
Police are investigating whether the attack is linked to other recent incidents in the area over the last couple of days.
The robbery also comes after another van was raided in Moulton earlier this month.
On that occasion, two men armed with an axe and a baseball bat robbed a Post Office delivery driver and escaped with a “significant amount of cash” contained inside a secure box.
The robbery happened on Friday, February 9, at about midday.
It is not known whether there is any link between the two van raids.
