MERRILLVILLE | Investigators continue to search for a suspect in a Friday morning armed robbery at Pawn King, 6850 Broadway.

Police said a man entered the business about 11 a.m., fired one shot into the floor and took an undetermined amount of cash and other items.

Witnesses said the man ordered customers to lie down, saying he did not want to hurt anyone. There were no injuries during the incident.

"He said, 'I just want to get what I came to get and leave,'" said Rose Dvojacki, of Merrillville, a Pawn King customer.

Police said the man was wearing a red sweatshirt. Dvojacki said the man covered his face with what appeared to be a bandanna.

He fled the business on foot after taking the items.

Merrillville police, Lake County canine teams and the Lake County helicopter unit searched the area.

A similar robbery occurred Dec. 29 at a Pawn King in Portage.

Portage police said the suspect in that armed robbery ran inside business at 2692 Willowcreek Road just after 11:45 a.m. Dec. 29 with a silver semiautomatic pistol and began yelling at employees to "get back."
