Ashley Tisdale's obsessed Twitter fan turns up at her home

The Los Angeles Police Department have launched an official investigation after an obsessed fan bombarded Ashley Tisdale with thousands of tweets, and then showed up at her home.

The police had started probing into the matter, after 18,888 tweets were sent to the star in November last year, the Sun reported

The suspect, who is believed to be a man, writes as if he has some kind of relationship with the 'Scary Movie 5' star.

One of his tweets read: "My body is yours and even as friends I f***** love how I make u feel like mom maybe we both got issues cuz nobody's perfect."

Another said: "I'll never lose u baby even in 20 years til infinity you'll always b my best friend."

In another he wrote: "Let it all out on me u can have my heart put a lock on it throw away the key and my soul is yours to keep."

The suspected super tweeter is said to have then shown up at Ashley's pad, although it's not clear whether he made contact.

A suspect has reportedly been identified and the police are looking to talk to him to find out if he poses any a serious threat to the star.
