A 23-year-old inmate at the Prince George's County Detention Center died early yesterday after he was involved in an altercation with another prisoner, officials said.

County police said they are investigating the death of Timothy Raymond Wall, who they said apparently refused medical aid following the altercation.

Wall, sentenced last week to three years imprisonment for assault and battery, apparently became involved in a dispute Tuesday with another prisoner who took some of his personal property, according to officials.

Later, a guard found Wall in a "disheveled condition with blood on his shirt" and asked him if he needed medical assistance, an official said. Wall refused aid, saying he had slipped in the shower, according to the official.

Wall was taken to the center's medical unit about 5:15 a.m. yesterday after a fellow inmate reported that he appeared to be having convulsions. Later, Wall was transferred to Prince George's General Hospital, where he died.

An autopsy is to be performed.

Corrections Director Arnett W. Gaston said that because of the "exceptional nature" of the incident, no stringent security measures were taken yesterday.

Wall was housed in a cell block for persons awaiting trial. Gaston said Wall would have been transferred to another part of the center soon because of his recent sentencing.
