Cops to Tom Cruise -- We Busted a Drunk Intruder at Your BH Crib

8:40 AM PT -- Sullivan is a self-described model and interior designer who appeared on a reality show in Australia about interior design.

Sullivan says he lives in a home next to Tom's place -- in fact, their backyards share a boundary.

8:17 AM PT -- Cops tell us ... Sullivan has been released and cited for trespassing. He has been ordered to appear in court next month.

One of Tom Cruise's neighbors got drunk, stumbled onto Tom's Beverly Hills property ... and then got zapped with a Taser for his mistake ... according to cops.

BH PD say the man, Jason Sullivan, drunkenly attempted to scale a fence at the Cruise home around 9PM last night ... and was met by a security guard who opened fire with a Taser.

When police officers arrived they caught Sullivan trying to run away from Cruise's house -- and the guard -- and arrested him for trespassing.

The Taser jolt messed up Sullivan badly enough that paramedics had to take him to a hospital for treatment. Cops say 41-year-old Sullivan actually lives in a home "adjacent" to Tom's ... and, due to "intoxication," may have gotten confused and entered the wrong property.

Tom was not home at the time of the incident.
