The Los Angeles Police Department says they’re investigating a report by TMZ about a knife found buried on the property of O.J. Simpson some time after Simpson was acquitted of murdering his wife and her friend.

“We don’t have any information on that,” a LAPD spokeswoman tells PEOPLE of the report. “We don’t know where [TMZ] got that story from. We have a captain who’s trying to determine that this morning.”

According to a new TMZ report, a construction worker found a folding Buck knife on the perimeter of O.J. Simpson’s former Brentwood mansion. The TMZ report is unclear about when the knife was allegedly found, with theories ranging from “several years ago” to 1998, the year the house was demolished.

The man took the knife to a police officer who was working nearby, and the off-duty cop kept the weapon, police sources reportedly told TMZ.

The officer allegedly never turned over the knife to the department, and planned to frame it for display in his home after retiring, the report states. The officer even wanted to get the departmental record for the murder case of Nicole Brown Simpson and Ronald Goldman, which he wanted to engrave in the frame, the report states.

After a friend found out, however, the policeman was allegedly ordered to turn it over, the report states. TMZ said that the knife is now being tested for hair and fingerprints, and will undergo tests for DNA and other biological evidence next week.

TMZ also reports that the knife could have blood residue on it.

Simpson was cleared of criminal charges in the 1994 murders of Nicole Brown Simpson and Ronald Goldman.

The case has recently received renewed interest thanks to FX’s new series starring Cuba Gooding, Jr., The People v. O.J. Simpson: American Crime Story.

Simpson resided at the estate in question when Brown and Goldman were murdered in 1994. He was evicted from the home in 1997 after defaulting on the mortgage, and it was demolished the next year by new owner Kenneth Abdalla, according to the Los Angeles Times.

“It’s part of my past,” Simpson told the newspaper of the home’s destruction at the time.
