DOVER — Two arrests were made and a loaded stolen revolver located after a downtown Dover chase early Friday morning, police said in court papers.

According to Dover police in an affidavit of probable cause, the incident began at 1:40 a.m. when a suspect wearing a ski mask allegedly put a handgun into a person’s face near the intersection of South American and Division streets and reportedly said, “Give me all your (expletive).”

Police alleged the suspect had exited the rear passenger seat of a light-colored Chrysler 300 vehicle that had approached head-on the person who was walking toward U.S. 13.

The car had first passed the person heading westbound and then made a U-turn before passing by eastbound, papers said.

Headphones, a wallet, cellphone, identification card and book-bag were turned over to the alleged assailant, authorities claimed.

Authorities said Wesley College security was contacted and then Dover police. A general broadcast about the alleged incident was made, referencing a light-colored Chrysler 300, according to documents.

According to police, a patrol officer spotted a vehicle matching the earlier description traveling near the area of North State and Division streets, and a pursuit began.

In the first block of North State Street, police alleged, people exited the vehicle and ran westbound toward Wesley College.

Another responding officer “was in the area and had eyes on the subjects and called it out as officers gave chase,” according to documents. People were seen in an alley between North Governors Avenue and North New Street, police said, and ordered to the ground.

The suspects continued running westbound, police said, and pursuing officers then took two people into custody.

In papers, police said an officer’s uniform top and pants sustained damage of $129.50 when the officer tripped and fell while attempting to take the suspects into custody.

Police alleged that one person was found with a bank credit card belonging to the person who initially had been approached. Ammunition allegedly was found on the other chase suspect.

According to authorities, headphones, cellphone and contents of a book-bag were found inside the Chrysler 300, all allegedly property of the person who had been approached.

In documents, police said a loaded silver Smith and Wesson .44 magnum revolver was located in the rear pocket sleeve of the front passenger seat of the Chrysler 300. Two ski masks also were located, police said.

Dover police said a check found that the revolver had been stolen out of Queen Anne’s County, Md., and the serial number had been altered.

Kyle Colliver, 20, of Jessup, Md., and Joseph L. Murray, 24, of the first block of Wooded Way in Dover, were both charged with first-degree robbery, possession of firearm during the commission of a felony, possession of a firearm with an altered serial number, aggravated menacing, disguise, receiving stolen firearm, second-degree conspiracy, criminal mischief under $1,000, and resisting arrest.

Mr. Murray also was charged with possession of firearm/ammunition by person prohibited and criminal impersonation. Police said in papers he had been convicted of a handgun-related felony in June 2012. Also, police said, Mr. Murray attempted to “defraud law enforcement officers from discovering his identity.”

Mr. Murray was arraigned at Justice of the Peace Court 7 in Dover and held in detention in lieu of $65,200 secured bail.

Mr. Colliver was arraigned and held on $31,850 secured bail. Preliminary hearings were scheduled for Friday.
