A man who rode through Leighton town centre naked on a motorbike on Sunday morning was detained under section 136 of the Mental Health Act.
The man, a 20-year-old from Leighton, was said to have exposed himself to a number of people before calls of concern for his safety were made to police at 10.30am.
Officers stopped the man on Bridge Street ten minutes later and after meeting strong resistance they used PAVA spray to help restrain him.
The 20-year-old was taken to Luton and Dunstable Hospital and is under the care of mental health experts.
He has not been charged with an offence.
