Three of the four people recognised this as a scam, which has previously been reported in the Herald, and refused to give details.

One however, did not realise until it was too late and had money taken from an account.

Police later arrested a 20-year-old man in Leicester on Saturday night in connection with the four cases of courier fraud.

He was taken into custody for questioning and later released on police bail pending further enquiries.

A police spokesperson advised: “Banks and police officers will never ask for account details or PINs over the phone, and would not come round to the house to collect your cards or property.

“If you do get such a call, hang up immediately and dial 999 using another phone.”

Investigating officers would like to hear from anyone who saw suspicious activity in the New Road area of Studley, Aston Cantlow village, the Church Lane area of Barford or the Malthouse Lane area of Earlswood on Saturday.
