In scenes befitting of a sequel to Hot Fuzz, bystanders ordered Toby and Becky Eyre to get out the way as officers from Thames Valley Police chased the man through Hinksey Park in Oxford, just as the bride and groom were having their special pictures taken.
The interruption came five minutes into their shoot with photographer Annie Crossman, who said the officers had the awareness to shout "congratulations" from their car window as the vehicles went by.
Other officers pursued the suspect on foot, with some making their way back to greet the loved-up couple and have pictures taken with them once the drama had come to an end.
Mrs Eyre said: "We had the best time! Such a surreal story on our wedding day."
Not only did the officers ensure Mr and Mrs Eyre would have a truly unique wedding day album to treasure, their efforts also resulted in two arrests.
"A 43-year-old man from South Hinksey and a 36-year-old man from Oxford were arrested on suspicion of possession with intent to supply Class A drugs in connection with this incident," said a police spokesman.
"Both have been released under investigation."
Hinksey Park is a popular spot in the city, but more so for its quiet wooded setting and abundance of wildlife than the possibility of having a front-row seat to a police chase.
