Surveillance cameras along the Monon Trail, including one at the spot where 64-year-old man was attacked over the weekend, are out of order, police said.
Two of the four cameras along the Indianapolis stretch of the trail are currently not working, officials with the Indianapolis division of Homeland Security confirmed to RTV6.
Officials did not say how long the cameras had been out of order.
The revelation comes days after Jim Knapp was riding his bike Sunday and was attacked in the 2100 block of the trail, suffering broken ribs, a broken clavicle, concussions and several cuts.
There is a camera at 21st Street and the trail, but it was not functioning at the time, officials confirmed.
Gary Coons, director of Indianapolis Division of Homeland Security, said even if the camera had been working, it still might not have been useful.
"Even if it were up at the time it might not have caught that if somebody wasn't watching that specific camera at that specific time or if the camera were in a different direction at that time," Coons said.
Knapp's family told RTV6 he was only carrying his cell phone and $3 when he was beat up and robbed.
Charles Tewell, a security officer at a nearby church, said he heard a loud noise and saw three teenage boys on bikes riding quickly away from the Monon.
"I was on the corner of my church area there and I heard the screaming in I saw the man laying in this area," Tewell said. "It's just disgusting that on Sunday afternoon you can't find anything else better to do than to wait on the Monon Trail to find someone to jump."
Indianapolis homeland security officials said an emergency order to repair the cameras has been placed.
A contract for regular maintenance expired in 2010 and, as a result, officials said repairs have been delayed.
"Funding is tight and you've got to fund what you can and do what you can with what you have," Coons said.
Indianapolis homeland security officials said the agency has found money in its own budget for the immediate repairs of the broken cameras.
Knapp's family told RTV6 he is doing better and was at home Tuesday.
