My daughter left her locked A3 (59 plate) outside her home in W London for 3 days while abroad.

On her return and on getting into the car she immediately noticed the glove box contents on the floor and the rear seats collapsed forward and the boot contents disturbed- not as she had left it. There is no evidence of a breakin, no damage and both sets of keys are accounted for.. The car was locked before getting into it (this is independently verified by a passenger).

The pollce are not interested except by issuing a crime No. This is worrying as it is clear someone has a means of unlocking/locking this car - any idea as to what has gone on?
