A Sheffield woman gave birth to her baby with the help of a passing police officer and special constable - after going into labour in her car.
Rachel Suter was about to give birth in her car when her 'frantic' partner spotted police officers on patrol and flagged them down to help.
Using Facebook to thank the officers, from the B Group Local Policing Team at Ecclesfield, Rachel said: "Thank you so much for your help. We are both now doing well in hospital.
"Thank you again. Bet you weren't expecting this on your shift."
A South Yorkshire Police spokesman said: "Whilst out and about on patrol PC Priest and SC Briggs were flagged down by a frantic male.
"Little did they know that his wife was in the car giving birth to their baby.
"Not one to be deterred by the unusual situation, Special Constable Briggs sprung into action, helping mum and baby and PC Priest ensured an ambulance, or two, were called to assist.
"So, to mum, dad and baby, a huge congratulations from the whole of the B Group Local Policing Team at Ecclesfield."
