Metro police officers are trying to figure out who robbed a couple on a walk on the canal in downtown Indianapolis overnight.

INDIANAPOLIS (WTHR) — Police had ordered more patrols in recent months on the canal in downtown Indianapolis after several attacks earlier in the year.

Now, a couple says they were attacked early Tuesday morning while walking along the canal.

According to a police report, four men surrounded the couple around 2:00 a.m. Three of the assailants had guns.

The couple told police the men demanded the man's cell phone and credit card and took cash from the woman before running away.

"It's a little scary as someone who lives around here and uses the canal and walks around here a lot," Kelly Fengya said Wednesday. She was walking her dog, something she says she does every day... just not late at night.

"Unless it's the middle of the day or broad daylight, I'm never out here alone," said Fengya. She added her husband is often with her.

'You just gotta be smart. I wouldn't be out here at 2 a.m. alone," said Ally Gold, who's in town for Gen Con. She says if she comes back to the canal, it will be during the day.

"During the day I feel safe," she said.

"I feel like whatever time we walk or whatever we doing, that's what we do," said Kim Williams. "We should still be safe at the end of the day," he added.

That hasn't always been the case this year, with two armed robberies after dark along the canal in March. Another couple was robbed and attacked in April They told police three teens attacked them.

Police say when officers with the downtown district are not on runs, they are patrolling the canal for safety.

For Williams, the canal is where he comes for peace. He's got a message for anyone disturbing that.

"You wanna come down here and mess it up? Why? What for?" said Williams.
