Business owners in a busy corridor of Melbourne are complaining about "zombies."

Not the movie variety, but vagrants and panhandlers suspected of being under the influence and causing problems.

"We call them 'walkers'," said Melina Champion, who works nearby.

"They look like they are on drugs, like they're zombies, just walking around asking people for money," said Brittany Ganswith, who works with Champion.

The co-workers have heard and seen first hand what so-called "zombies" are doing in their business parking lot near Wickham and Sarno Roads. They say it's scaring customers when they step outside.

"It makes us uncomfortable as well. Just to even go outside on our breaks and stuff," added Champion.

The problem has been happening for about a month or so, dozens of calls about loiterers and aggressive panhandlers.

"The people that loiter, sitting on sidewalks, sitting on their benches, in their parking lots," said Commander Vincent Price of the Melbourne Police Department. "Some have even called them zombies."

One of the many complaints talks about four to six people loitering in the Twin Oaks Plaza, calling it an ongoing issue with "zombies," acting lethargic and possibly on drugs.

"I open the door and they are smoking K-2 right at our backdoor," said Sam Adams. He owns a smoke shop, but doesn't sell K-2, a legal synthetic cannabis also known as "Spice."

In the past month he's called police at least 14 times for trespassing and had customers tell him they are being harassed and not coming back.

"It's not a good feeling, but I'm trying to run a business here," he said.

Some can be arrested for trespassing or loitering. If they are panhandling aggressively, a new ordinance passed in Melbourne last month allowed police to arrest them for that as well. But all of these charges are minor.

Monday night Melbourne Police arrested 31-year-old Dustin Jolly during a foot patrol. They said he was aggressively asking nearby Wal Mart customers for money. They found a needle filled with heroin and K-2. He was taken to jail.

Police continue patrols of the area, and encourage local business owners to keep calling if they see anything suspicious.
