PHONES, a wallet and clothes were among the items stolen as thieves broke into six vehicles at a High Wycombe school.

Police said thieves forced their way into six vehicles parked at John Hampden Grammar School between 9pm and 10pm on Monday.

Investigating officer PC Chris Flowers said: “I am appealing for anyone who witnessed the thefts to contact police.

“I would also like to speak to anyone who saw any suspicious activity in the area at around the time of the incident.”

An iPhone 5 was taken after the lock was forced on a Volkswagen Polo.

Thieves pinched a black Superdry jacket from a silver Ford Fiesta after the front driver’s side window was damaged.

The lock was forced on a Fiat Punto and a black iPhone was stolen from the glove box, while keys were swiped from a grey Audi A3.

Thieves also cracked the lock on the driver’s door of a grey Volkswagen Fox to grab a gym bag containing sports clothes.

Finally, the passenger window of a blue Audi A4 was smashed and a Samsung Galaxy S3, a wallet containing a small quantity of cash, debit and credit cards and a driving licence were stolen.
