A few days after the Houston Chronicle reported that a haunted house had been found in the same building as a recent shooting death, the FBI is warning of another.

The FBI said Friday it is also aware of a report of a possible sighting in the Houston area.

Houston Police Department said the agency was notified by the Federal Bureau of Investigation in late March that an unknown person had been seen in a vacant lot in the 400 block of South Main Street, near Interstate 610.

The report is still under investigation.HPD Capt. Edna Broussard said a woman and a male were spotted walking in the parking lot after dark on Tuesday and were questioned by HPD officers who were there when the sightings were reported.

The man was later taken into custody and booked into the Harris County Jail on charges of possession of marijuana, possession of drug paraphernalia and possession of a firearm by a convicted felon.

Houston police did not immediately return a call seeking comment.
