An alleged "stalker" was arrested this weekend after breaking into Madonna's home.

Grzegorz Matlok, 29, was wrestled to the ground by bodyguards at the 52-year-old star's £10 million 10-bedroom mansion in London's Marylebone area at 5.30am on Saturday morning (12.03.11) after being found clutching several of the 'Material Girl' hitmaker's possessions.

Despite having a huge security team and a state of the art CCTV system in place, the intruder ' who the singer's bodyguards told police was a "stalker" ' gained entry to the Georgian townhouse by smashing a side window while the singer was in the US mourning the death of her grandmother Elsie Mae Fortin.

A senior police source told The Sun newspaper: "Something dreadful has happened here. The security around the world's most famous pop star should be impregnable."

Polish-born Matlok was charged with burglary last night (13.03.11) and is now due to appear before magistrates in Westminster today (14.03.11).

At the time of the break-in, Madonna ' who has four children, Lourdes, 14, Rocco, 10, Mercy, six, and five-year-old David ' was in Bay City, Michigan, paying her respects to her late 99-year-old grandmother, who helped raise the singer and her five siblings after their mother died of breast cancer when Madonna was just five.

This isn't the first time the pop superstar has been plagued by a stalker.

In September 2010, retired fire-fighter Robert Linhart was charged with criminal mischief, graffiti and being in possession of a homemade 7.5 inch ice pick, after writing messages to Madonna on the pavement outside her apartment in Upper West Side, New York City.

The messages read 'Meet me please', 'Tell me yes or no', and 'If it's yes, my dream will come true. If it's no, I will go.'

According to court documents, he reportedly told officers: "I can be here. This is police brutality. I have a right to do this. I am not doing anything wrong. I keep running into Madonna. I saw her in 1992 and I'd actually like to meet her in person. I won't stop until I actually meet Madonna.

"I'm going to go right back there and do it again."
