The ambulance, under 108 service, equipped with a ventilator, echo-cardiograph machine, defibrillator and paramedical staff used to be parked outside 10 Circular Road, the official residence of former Chief Minister Rabri Devi, where Tej Pratap lives with his parents.
The ambulance has been removed from 10 Circular Road, Patna Civil Surgeon Virendra Prasad said.
Earlier, Tej Pratap said, "It was meant for service of people who come to meet me at the residence."
As per rules, an ambulance can be stationed only at the houses of the Governor and the Chief Minister and it joins their cavalcade.
Patna district has 10 elite ambulances under 108 service, out of which nine are presently functional. With one kept at the minister's residence, the public had access to only eight ambulances.
