Lohan Suspect -- Accused of Burglarizing Audrina

Cops believe 18-year-old Nicholas Prugo broke into Audrina's Los Angeles home back in February ... and then Lohan's pad in August.

In both instances, security cameras captured several people entering the homes -- one of those people was a young male wearing a baseball cap and a t-shirt.

Prugo was arrested earlier today on suspicion of burglary -- a felony. He's currently being held on $20,000 bail.
