Assistant Commissioner for Security and Intelligence Mark Wilson PSM said that while some drugs were allegedly discovered on visitors, it is also an offence for visitors to have banned items in their cars when attending the complex.

“Anyone visiting a correctional centre needs to be aware that officers and K9s are out in force conducting contraband screenings and this includes searches of any property brought on site,” Mr Wilson said.

Visitors caught bringing banned items, including illegal and prescription drugs, to correctional centres face penalties of up to two years' imprisonment.
