Phone scammers impersonating Amazon staff are still targeting Oxfordshire residents, police have warned.

Earlier this week a North Oxford resident was targeted by the fake callers.

When she picked up an automatic message said: "You have been charged £89 for your Amazon shopping.

"If this is true, please dial 1, to speak to an operator. If you put the phone down, you will be charged £89 and the goods will be delivered."

Thames Valley Police put out an alert today asking residents to stay vigilant. 

"Don't become a victim of that trap, and remember scam is UK number one crime", officer Ahmed Mohamed warned.

Amazon's customer service confirmed its staff will never ask for people's personal information, or ask them to make a payment outside of the website.

In October last year police also warned against fake Amazon Prime subscriptions.
