Two phone calls to police about a masked man in Union Township with a weapon inside the Walmart proved unfounded, officials said.

The store in Union County on Springfield Road off Route 22 was evacuated after police received the first of two calls at 10:48 a.m., police director of the Union Dan Zieser said.

Police searched the store from top to bottom and discovered “absolutely nothing,” said the director.

The first call came from a cellphone, he said the second came from within the store. Investigators discovered the first caller and interview the person, officials said. To determine who placed the second call, the police are still working on it.

In an evening news conference, Acting Union County Prosecutor Lyndsay Ruotolo said one of the calls was made by a person who saw someone holding what turned out to be a toy gun. Earlier that person was seen chatting about a prospective threat on social media, said the prosecutor.

Employees were back around 1:20 p.m. in the store. Customers were expected to be admitted shortly after.

Roro Lindor said he was shopping in the back of the store when police were screaming about evacuating customers.

“I didn’t want to take any chances,” the Union resident said by phone minutes after leaving. “I just got out of there. They wanted everyone to drop everything and go. If you were shopping and heard someone had a gun, what would you do?”

Lindor said as people raced to the exits, the store was busy.

Walmart spokeswoman Lemia Jenkins verified that there was no gunman in the Walmart and referred all other questions to Union Township police.
