GLASGOW Prestwick Airport is to install a £250,000 hi-tech security scanner to replace the existing walk-through airport security metal detector.

Prestwick Airport's security manager, Ian Gregory, said: "As part of our ongoing customer commitment, we've listened carefully to passengers' comments.

"They asked that the operation at our search facility remains fast, efficient, friendly and stress-free, and the new equipment will help us meet their aspirations."

He added: "The technology uses automatic threat recognition software which interprets the scan data instead of creating an image and identifies areas where items may be concealed on the body.

"These areas are flagged on a standardised stick-figure on a screen to indicate to the security officer areas of the individual's body which should be checked.

"As privacy and confidentiality are paramount, all data relating to the individual is destroyed after the scan is completed."

Initial trials of full-body scanners at Manchester airport since 2009 proved controversial as they produced a detailed, ghost-like image of the naked body, which was viewed by security staff.

The device is due to installed in the spring.
