It is a criminal offence to clamp, tow, block-in or immobilise a vehicle without lawful authority on private land under the Protection of Freedoms Act 2012. Lawful authority to immobilise or move a vehicle is restricted to a number of organisation such as the police, DVLA and local authorities.
To commit this offence a person must intend to prevent the owner/driver from moving their vehicle.
Well Op hasn't done any of these things. She simply shut and locked her gate - after telling him that is what she will be doing and gave him time to move his car.
He CHOSE to ignore her and leave it there.
She has also tried to locate the CF and subsequently been in contact with him to arrange a time for him to collect.
He CHOSE to turn up when she said she wouldn't be there to unlock the gate.
He also CHOSE not to turn up when she said she would be there.
He also still hasn't apologised. And also now has hundreds, if not thousands, of women around the world thinking he is a knobhead.
And honstly I think hes damn lucky it's OP's land he chose to park on, because I think there's a fair few of us that would've let the twats tyres down by now.
