BRADLEY STOKE, England — James Edwards, who operates a legal adult production studio in his four-bedroom home, has aroused the anger of his neighbors, who have demonstrated outside his house with placards claiming his business is lowering the value of their property.

Edwards, who has been in the adult entertainment business for 10 years, said, "When you look at the house, you can't actually see that there's anything going on. All right, there are girls visiting and there are camera people coming in and out but they are all clothed when they come out."

A spokesman for Avon and Somerset police said, "We believe the occupier is legitimately running a pornographic recording studio."

Neighbor Peter Kite was taking part in the protest.

"The police say it's legal but they don't see everything," Kite said. "If you've got pornography here now, you're going to have prostitution next, you're going to have drugs. In a residential area? No way. No way."

Bradley Stoke Mayor Rob Jones invited the protesters to report any illegal activity.

"It can't be good for the neighbors to have this on their doorstep," Jones said. "I've got a lot of sympathy for that. If there are grounds for complaints under antisocial behavior or trading standards then by all means come to the council and we'll investigate."
