London, England (CNS) - Canadian rock star Bryan Adams has called in the police after allegedly being stalked by a mother and son tandem.

The 49-year-old singer is said to be "very concerned" after the pair keep on turning up at his home and destinations for weeks.

A source told The Sun, "They have become obsessed with Bryan, turning up at his house and stalking him everywhere."

"It started when they saw him in a restaurant. Bryan likes to keep a low profile and is hardly the most recognizable rock star."

"He was happy to sign an autograph, but this mother and her son have become obsessed with him. He doesn't want them to get in any serious trouble, but he wants to be left alone."

The unnamed mother and son duo are believed to have come from Romania and are suffering from psychiatric problems. The authorities have given the Grammy Award winner safety advice and a panic alarm has been installed at his Chelsea home.

No arrests have been issued and investigation and inquiries are currently being held.
