The incident took place at about 1.30pm today (Thursday) after police chased a ‘car of interest’ as the helicopter followed the procession.
The car stopped at Great Doddington with the suspects running off, but after a foot chase four were arrested.
A force spokesman said they are currently in police custody and inquiries into the incident are ongoing.
The spokesman added that the road was shut for about 10 minutes while the incident took place. It has now re-opened.
