Penny Lancaster has made her first arrest as a serving police officer.
Lancaster, who is married to Rod Stewart, started working as a special constable with City of London police last year after passing her training.
The model and TV presenter works 200 hours a year in the role and her first arrest was a drug driving suspect.
She revealed that she was on mobile patrol with a colleague when they pulled a car over. A roadside breath test later revealed the driver to be under the influence of cannabis.
Lancaster then made the arrest and took the suspect into custody.
Talking on Loose Women, Lancaster said she nearly forgot how to read the suspect their rights: "I did get a bit of a stage struck moment where I felt all the words of the caution had left me but luckily they came into action and all my training proved important there."
Lancaster took the jump to be a special constable after taking part in reality TV show Famous and Fighting Crime where she would shadow police officers on the job.
The Loose Women panellist previously appeared on Crimewatch Live to discuss her role, saying: "It's predominantly foot patrol but I also get the opportunity to try other areas of policing out like working in vehicles, working with the sniffer dogs and operations like the London Marathon, the Lord Mayor's Show and coming up the Jubilee."
She also said that Stewart is supportive of her passion for policing though he does worry for her safety. She said: "He worries about the natural risks involved but with the support I've got around me, and letting him know when I'm back at the station and safe to head home, he's able to go back to sleep."
Lancaster's 200 hour role is the equivalent of around one week's duty for an ordinary officer.
