Two men have appeared in court charged in connection with a series of carjackings across the south east.
Richard Todd, 37, and John Todd, 33, both of no fixed address, were charged with more than 20 offences.
They include kidnapping, aggravated vehicle-taking and being in possession of a loaded firearm.
The pair, who were remanded in custody, appeared at Reading Magistrates court on Tuesday.
They are due to appear in court again next week.
A Thames Valley Police spokesman said the incidents began just after 1200 BST on Friday.
A number of vehicles were said to have been taken over nine hours from Buckinghamshire, Berkshire and Oxfordshire.
