Paramedics and police were called to a bus in Dundee city centre after a woman was feared to have suffered an ‘overdose’.
Emergency services were called to the scene on Nethergate where the number 73 Stagecoach bus pulled over at around 12pm.
Passengers had to be transferred on to other buses while the woman was treated on the top deck of the vehicle.
One person who was on the bus described the seeing the woman, who was in the company of a man, getting on the Arbroath-bound service.
He said: “They seemed to be staggering a little but seemed okay. They went up stairs but a short time later the man came down and said he couldn’t wake his partner up.
“He said he thought she had overdosed.
“Everyone else got off the bus and paramedics arrived just a minute later.”
A spokesman for Stagecoach East Scotland said: “Unfortunately one of our passengers took ill on board our 73 service. Our conductor on board called an ambulance which attended along with the police and the remaining passengers were transferred to an alternative vehicle to continue their journey.
“We are thankful for the reactions of our driver and conductor and we wish the passenger a speedy recovery.”
A spokeswoman for Police Scotland said: “Police Scotland was called to a bus on Nethergate after reports of concern for a woman.
“Ambulance personnel attended and dealt with the incident.”
