Amy Winehouse's collapse was caused by her drink being spiked by ecstasy, The Sun claims.

Amy Winehouse's drink spiked with ecstasy?

A source is quoted as saying: "Mitch is furious. He's certain someone put E in Amy's drink - and he's determined to get to the bottom of it. He is convinced that one of her hangers-on was responsible and he's waiting for a toxicology report to show what caused her to fit.

"If his suspicions are proved right, he wants someone to be punished. He is seriously unhappy about Amy's flat being a stop-over for randoms and wants an end to it."
