LAPD sources told TMZ that while it is always vigilant during the Academy Awards, there is "an extra knot" in security this year.
The move is apparently in response to the wave of high-profile shootings that have occurred across America in recent months.
Describing the current climate at the department, a source said: "When someone from the city gets fired, the city manager of the department calls because they're scared the person who was fired will go postal. People are going crazy with fear."
The LAPD has given private security company Security Industry Specialists (SIS) details of all stalkers known to be harassing stars who are attending the Oscars.
The information packets include pictures of the stalkers, which will be given to security on site.
