A stalker who spent six nights undetected in pop star Jennifer Lopez's $10m Water Mill home has been arrested. Lopez already has a protective order against the man, 49-year-old John Dubis, who is a retired fire-fighter from Rhode Island. The man retired from the East Greenwich, RI, Fire District in November 2002 due to disability.

Dubis allegedly sneaked into Lopez's home in early August and posted photos of her property on the internet.

"Oh, my, come to think of it, I did find it odd when I saw a man standing outside her driveway with the gate closed. I figured he was just part of her security crew. It's really frightening - you don't want to be a celebrity. I'm telling you, it's a curse. I just hope [J.Lo] gets to enjoy this place just like everybody else," Nancy Haverman, Lopez's neighbour, stated.

According to Reuters, Lopez's eight bedroom mansion sits on three acres of land, has about 8,500sq ft of living space with multiple bathrooms, a pool and guest house, a media room and a sauna. It is situated in Southampton Hamlet, one of the most expensive pieces of residential real estate in the United States.

Dubis was later arrested and charged with burglary, stalking, criminal contempt and possession of burglary tools, according to police. He is being held in the Suffolk County Jail on $100,000 bail. His next appearance at the court is scheduled for 28 August, according to the chief court clerk, DeBorah Renee Brathwaite. The police stated that he entered a not guilty plea after arrest. They also released a statement that the court has ordered an examination to determine if Dubis is fit to stand trial for the criminal charges.
