AN intruder reportedly broke into the Scottish Parliament building, managing to bypass security measures including metal detectors, biometric scanners and anti-terror measures.

According to the Mail on Sunday, in January a man climbed a fence and was able to walk in late at night when ministers and MSPs were not working.

After security staff saw him on CCTV, the man was ejected and police were called.

The alleged intruder would have been unable to access the main Scottish Parliament Chamber, and other key rooms were locked, a source said.

The cross-party Scottish Parliamentary Corporate Body said back in January that it could review the Parliament’s security measures.

Later in the year it announced Holyrood would be designated as a protected site, giving police extra powers to stop “disruptive” protests there.

A Scottish Parliament spokesperson said: “There are live proceedings. We cannot comment.”
