CHARLOTTE, N.C. -- There has been a new frightening encounter with a suspected serial armed robber.

A Subway employee is speaking out, after being held at gunpoint at the Park Road Shopping Center. Police say that’s the seventh armed robbery in three weeks by the same suspect.

It happened Monday afternoon, just a few hours after the Charlotte Mecklenburg Police Department held a news conference about the armed robberies.

The 19 year-old victim at Subway tells NBC Charlotte she’d actually seen the news stories about the serial armed robberies, but she says she had no idea she was facing that suspect, until she talked to police.

CMPD provided new surveillance photos from the Subway armed robbery, which happened around 4:40 p.m. on Thursday.

The victim asked NBC Charlotte to hide her face as she described the frightening encounter.

“He pointed the gun like at my midsection area right in here, and I just immediately froze and was in shock, like I can’t believe this is happening right now,” she told NBC Charlotte.

Just a few hours earlier, CMPD held a news conference about the suspected serial armed robber.

“We just need to build a case and stop him, frankly before he hits again,” said Sergeant Brian Scharf during Thursday’s news conference.

Police say the same man targeted six other businesses, ranging from Dairy Queen and Smoothie King on Prosperity Church Road to Starbucks on Providence Road. The latest victim at Subway says she saw the previous news reports.

“I don’t recall seeing the face of him, so it didn't even register this was going down in my store,” says the victim.

She says she was working alone at the time with one customer in the store, who she believes acted suspiciously during the armed robbery.

“He (the customer) didn't even turn around or flinch,” says the victim. “The customer left and then the suspect left right after him, it was no more than five or ten seconds, so that was what was suspicious to me.”

CMPD tells NBC Charlotte they’re investigating all possibilities. Meanwhile, police are adjusting resources to the areas that have been targeted. Officers are also talking to businesses about the armed robberies.

“I would most definitely advise other employers, if you only have one employee in the store, I would at least double up that,” says the victim.

CMPD is offering up to a $1,000 reward in the case. If you have any information you’re asked to call Crime Stoppers at 704-334-1600.
