DALLAS — Police nabbed two suspects and were looking for as many as two others who allegedly stole an ATM from a convenience store in Seagoville early Friday.

The missing bandits are believed to be armed and dangerous.

Store manager Joyce Dunlap said clerk Marian Campos, 51, had been cleaning and was putting away a mop bucket when a car drove through the front window of the OneStop food store in the 200 block of Hall Road at U.S. 175 around 2 a.m.

The robbers — wearing black clothes and ski masks — jumped out of the car, and one held a gun to Campos’ head, Dunlap said.

They shouted at her get down on the floor and then yanked out the bolted-down ATM.

As the robbers sped away, they nearly collided with an off-duty police sergeant who just happened to be driving by the convenience store, said Seagoville Police Chief Pat Stalling.

Someone in the getaway car fired a shot at the officer’s car, striking the driver's side door. The officer, who was in uniform, was not injured and did not return the gunfire, the chief said.

"The violence they displayed in this case was troubling," Chief Stallings said. "They held a clerk at gunpoint and shot at a police officer."

Backup units chased the suspect along Interstate 20 into Dallas, where Dallas police joined the pursuit.

The chase ended 13 miles away when the fleeing vehicle crashed at Gateway Park in the 2600 block of North Jim Miller Road.

The suspects disappeared in the adjacent Keeton Park Golf Course.

A SWAT team and police officers set up a perimiter around the park.

Two suspects were captured after 5 a.m. Police suspended the search for two other suspects about three hours later.

Dick Morrill, an area supervisor for OneStop, said he didn’t know how much money was in the ATM. But, he said, police told him that the machine’s cash canister was intact.

“Hopefully, the money is still there,” he said. “The unit was destroyed, and those things are not cheap.”

Ms. Dunlap said the clerk, Ms. Campos, was doing fine. "She’s very calm," Ms. Dunlap said. "After she goes home and relaxes, it might hit her.”

Patsy Fanning, 67, of Forney is a regular at the OneStop. She said the shopping strip is generally quiet. But, she added, with the bad economy and the frequency of ATM thefts in North Texas, a crime of this sort in the area was almost inevitable.

"Its all over the news every day," she said. "They are breaking into stores and taking those ATM machines all the time. It doesn't surprise me it happened here."

Another patron, Charles Davis, 50, of Mabank, agreed.

"Crime happens everywhere now," he said.

Dallas police said they were alerted to three additional ATM theft reports on Friday morning.

Last week, Dallas police raided a house where they found what was termed an ATM "chop shop." Five suspects were taken into custody.
