A man accused of leading state police on two high-speed chases through Butler County has 100 felony charges being filed against him in his most recent case.

A lengthy pursuit on Sunday led to the discovery of a backpack containing 100 glassine bags of suspected heroin and police charging Delvante D. Thompson, 35, with 100 counts of felony drug sales, felony fleeing an officer, two counts of misdemeanor use and possession of drug paraphernalia and several traffic citations.

Early Sunday, Thompson was arrested, charged and placed in Butler County Prison in lieu of $150,000 bail.

State police from Troop B Pittsburgh reported a silver Chevrolet Malibu traveling north on Interstate 79 in Cranberry Township at a high rate of speed. They discovered the vehicle was fleeing other state troopers.

When police attempted to initiate a traffic stop at mile marker 98 in Muddy Creek Township, a pursuit ensued.

An object was thrown from the front passenger window of the vehicle, police observed, around mile marker 100.7.

State police from the Butler barracks deployed spike strips farther up the road and deflated the vehicle’s tires. The vehicle slowed, but the pursuit continued.

Police said a PIT maneuver was conducted to stop the vehicle. Known as a precision immobilization technique, the PIT maneuver is used when a law enforcement vehicle forces a suspect vehicle to turn sideways and stop during a pursuit.

The male driver inside the vehicle refused officers’ orders to exit, police said, and a window was broken to remove the man, later identified as Thompson.

Other troopers responded to mile marker 100.7 to retrieve the abandoned item: It was a black backpack containing 100 glassine bags of suspected heroin, as well as identification for Thompson, police said.

Thompson’s preliminary hearing before District Judge Joseph Nash is scheduled May 3.

Last month, Butler state police said they were investigating a silver Chevrolet Impala that had eluded a traffic stop. The driver later was identified as Thompson.

According to documents filed Sunday, the Impala ran a red light at the intersection of south Route 8 and Dinnerbell Road around 6:45 p.m. March 26.

Police attempted to initiate a traffic stop when the vehicle accelerated and a chase began. The chase continued through Penn and Middlesex townships in Butler County and Richland, Hampton and Shaler townships in Allegheny County.

Around 6:58 p.m., police said the Impala proceeded through a red light at the intersection of Route 8 and Mount Royal Boulevard, Shaler Township, Allegheny County, striking two pickup trucks.

The Impala slowed down due to the crash, and police attempted a PIT maneuver to stop the vehicle. The attempt was unsuccessful, and police decided to terminate the pursuit in order to ensure public safety.

During the chase, the Impala was recorded traveling 110 mph in some areas, weaving into other lanes 10 times, driving into oncoming traffic seven times and running several red lights.

Police identified the vehicle’s owner as Thompson, and attempts to contact him at his home were unsuccessful. When police phoned Thompson and asked him to discuss the incident, he hung up on them.

Cellphone records obtained by police showed Thompson’s phone traveling with the route consistent to the pursuit on March 26.

In this incident, Thompson was charged with felony fleeing an officer and traffic citations for reckless driving, careless driving, prohibited passing, failure to stop at a red light, disregarding a traffic lane and others. He was placed under an additional $10,000 bail.

Thompson’s preliminary hearing before District Judge Sue Haggerty is scheduled April 26.
