LAKE MATHEWS, CA — A Riverside County man who is reportedly obsessed with celebrity Kim Kardashian to the point of being served a five-year restraining order has been arrested in a separate case in which he victimized Lake Mathews residents and used the famous socialite's name in the process, authorities said.

Nicholas Scott Costanza, 25, of Lake Mathews was arrested Friday and has been charged in Riverside County with five felonies including aggravated stalking, residential burglary and vandalism. He's also been charged with eight misdemeanors including trespassing and violating a court order.

The Riverside County investigation began Sept. 15 when residents of a Lake Mathews home were awakened about 5 a.m. by Costanza yelling outside, authorities said. He told the homeowners he had been invited by Kardashian to a party at their residence, authorities said. When the homeowners told Costanza there was no party, he left, according to the Riverside County District Attorney's Office.

Three days later, however, while the homeowners were on vacation, Costanza snuck into their residence and damaged it, including using a black marker to scrawl graffiti, authorities said. The damage was estimated to be about $11,000, according to the DA's office.

A day after the alleged entry, the homeowners said they returned and found Costanza in a guest house on their property. Costanza told them that Kardashian gave him permission to be there, which was untrue, authorities said.

The intruder left, but as the victims surveyed their home's damage, they also discovered Costanza’s Instagram page, where he had posted videos narrating his takeover of their residence, they said.

On Sept. 20 — five days after their first encounter with Costanza — the homeowners were granted a temporary restraining order by a Riverside County Superior Court judge.

Serving Costanza with the order proved difficult, but he was finally tracked down in the Lake Mathews area in early October. Still, Costanza would not stay away, authorities said. On Jan. 7, the victims viewed Costanza on a security camera using bolt cutters on their security gate's lock. Three days later, a note from Costanza was found on their driveway stating he was “Lord God” and their home belonged to him, authorities said. The note demanded the homeowners leave the property and unlock their gate, according to the DA's office.

A DA investigator who interviewed the victims on Feb. 15 said the homeowners told him they feared for their lives, so much so that they had a gun at the ready, the DA's office reported.

Because Costanza did not comply with the Riverside County restraining order, he was arrested at 8:45 p.m. Friday in Lake Mathews, authorities said. He was booked into Banning's Larry D. Smith Correctional Facility, where he is being held without bail; he is scheduled to be arraigned Wednesday.

According to multiple media reports, in October Costanza was charged with felony stalking in connection with Kardashian after he failed to comply with the restraining order that was issued against him last summer in that Los Angeles County case.

Anyone who may have further information about the Riverside County case is asked to call senior DA investigator Billy Hester at 951-955-0070.
