Grzegorz Matlok, 29, was wrestled to the ground by bodyguards at 5.30am inside the heavily-fortified ten-bed Georgian townhouse.

He is said to have climbed in after smashing a side window while the singer was in the US following the death of her grandmother.

The security team told police who arrested Polish-born Matlok that he had stalked her before.

The huge home in Marylebone has an array of CCTV cameras and a state-of-the-art alarm.

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

Matlok, of no fixed address, was seized on Saturday.

Elsie helped raise five-year-old Madonna and her five siblings after their mother died of breast cancer.

Though Madonna saw Elsie in her coffin, she is not believed to have joined family at the church funeral service.

Madonna has had several stalkers. In October one was found with an ice pick after scrawling "Meet me" outside her New York apartment.

最近两周对天后麦当娜来说是霉运连连。她挚爱的祖母去世已经够让人伤心欲绝了；而就在麦当娜去美国密歇根州参加葬礼时，她在英国价值1000万英镑的豪宅被变态破窗而入，幸好及时抓获，没有造成太大损失。

据英国《太阳报》报道，警察在日前抓获了一名企图闯入麦当娜豪宅的波兰裔窃贼。而且该名窃贼不单是要盗窃，更曾经有因尾随麦当娜而被捕的前科。这次窃贼打碎窗子潜入麦当娜家中，却发现她并未在家，一无所获的同时，还将面临盗窃罪的司法指控。

名声在外的麦当娜粉丝众多，但其中也不乏变态之徒。2010年和1999年她都曾遇到多位行踪诡异的变态，所幸都化险为夷。其他名人，比如前披头士乐队成员乔治-哈里森甚至曾遭遇疯狂粉丝的刺杀。

麦当娜的祖母埃尔西在上周去世，麦姐带领自己的孩子去参加了祖母的葬礼。据悉，麦当娜与祖母关系很亲密，埃尔西在麦当娜母亲去世后就一手抚养她和几个兄弟姐妹，祖孙感情深厚。
