The online stalker allegedly has tried to meet the former 'High School Musical' star in person by showing up at her house.
Ashley Tisdale is allegedly freaked out after one of her followers on Twitter sent over 18,000 messages to her. TMZ reports that police is now investigating the matter after her camp alerted the law enforcement of the possible stalker.
The fan believed to be a man seemed to be delusional. He proclaimed his dying love to her as if they were in some sort of relationship. "Let it all out on me u can have my heart put a lock on it throw away the key & my soul is yours to keep," one of his tweets read.
The obsessed fan reportedly even went so far as to show up at Ashley's house, but it's unclear if he ever made contact with the former "High School Musical" actress.
A suspect reportedly has been identified by cops who are looking to interrogate the person to determine whether or not he poses a serious threat to the actress.
