Police and fire crews are on the scene of a possible hazardous materials incident at a pharmacy in Warren. 

Authorities blocked of roads around Sussex SavMor Pharmacy, on Van Dyke, just south of Nine Mile Road. 

Sharell Allen, a pharmacy employee, said the Fire Department was called at 4 p.m. when a person brought a large jar of ammonium nitrate into the pharmacy. 

Allen said the store has a display of old medicine jars and old remedies. The person had planned to donate the jar to the pharmacy for the display. 

"A patient brought in a bottle of ammonium nitrate that was larger than normal," Allen said. "We called the Fire Department once we opened the package, and he didn't realize what would happen ... It was a large quantity ... larger than what we would have accepted." 

Fearing it was a dangerous amount of  ammonium nitrate, authorities were called. As of 6 p.m., Warren hazmat crews are on the scene. The plaza has been taped off by police who have declined to comment on the situation. 

Ammonium nitrate is a chemical commonly used in agricultural fertilizers and is a highly explosive compound, according to

The compound was used by Army veteran Timothy McVeigh, who used more than 4,000 pounds of ammonium nitrate fertilizer and fuel oil to destroy the Alfred P. Murrah Federal Building in 1995, killing 168 people and injuring hundreds more. McVeigh was convicted of murder and executed by lethal injection in 2001 at age 33.
