The driver of a wildlife rescue ambulance was brought to a stop near Uckfield and then assaulted by a man who demanded drugs.
The ambulance was being driven along the A22 near Palesgate Common at around 11pm on Monday when it was overtaken by a dark coloured, older style, hatchback.
It slowed down and put on hazard lights bringing the ambulance to a standstill. Thinking that something was wrong, wildlife rescue volunteer Trevor Weeks got out of his vehicle, but was then assaulted and asked to handover drugs from the vehicle.
However, the wildlife rescue ambulance does not carry drugs or medical supplies.
This would appear to be an opportunist and very unusual attack, which has obviously left the victim very shaken.
"We would like to hear from anyone who may have seen the two vehicles in the Palesgate Common area on Monday evening, either driving or at a stop by the roadside. Please call Sussex Police on 101 quoting serial 1861 of 15/10."
