A bicycle thief targeting riders in Midtown Tulsa is leaving behind his mark.
FOX23 News has been following this story and found a string of bike thefts in Midtown Tulsa between 15th and 36th streets and Riverside Parkway and Harvard Avenue.
The thief is known to ride on an old bike, dump it at the victim's home and steal a new bike.
"It's an extension of yourself," said Davin Hallford with Lee's Bicycles. "Losing is like losing a family member, a pet or even a toe."
He hasn't had a bike stolen since he was a kid but FOX23 News wanted to find out how much the stolen bikes reported to police and on Facebook were worth.
"Those are like, $500 bikes or more," said Hallford.
One of the victims only had a black mountain/hybrid bicycle for a month.
The thieves traded it out for a junky bike you can buy at a department store or laying around for anyone to take.
"They are a dime a dozen. You can get one for $40,” said Hallford.
In Midtown Tulsa, where the thefts are happening, Peter Grant stopped a potential bike thief on Wednesday.
"He has no idea I'm checking him out," said Grant. "He then decides he's going to go for it."
Grant said he whistled at the thief when he touched his neighbor's back gate.
"I told him I'm calling police right now," said Grant.
He did call police, who showed up and took a report.
It was later discovered his neighbor had a bicycle in his greenhouse.
"He crossed a fence to get back here," said Grant. "He was trespassing."
The watchful neighbor didn't want to let another bike thief invade his neighborhood.
"I'm here and I hope my neighbors would extend the same courtesy," said Grant.
Bicycle thieves are known to sell stolen bikes at pawn shops. Depending on the brand, bicycles may or may not have a serial number for police to trace.
There have been several reports of bicycle thefts with different descriptions. Police said they arrested one a few weeks ago.
