A 26-year-old woman has been charged with a public order offence in connection with an incident where a foul-mouthed note was left on ambulance windscreen.
The crew were also allegedly subjected to verbal abuse after parking in a residential street while responding to a 999 call in the Tunstall area of Stoke-on-Trent at the weekend.
In a statement, Staffordshire Police said it had also charged Kirsty Sharman, who is from Tunstall, with breach of a restraining order.
Sharman will appear at the North Staffordshire Justice Centre in Newcastle-under-Lyme on Tuesday.
The arrest followed a plea on social media by ambulance staff, who reported how colleagues had found a hand-written note complaining that the vehicle was parked outside their house.
