Police said that the two men got into an altercation at the bus stop when one pulled out a gun and shot the other.
ABC13 talked to a witness who was heading to the bus stop, and he described what he saw.
"The guy was between the two stops, and he shot him there and he dropped to the ground, and everyone was slow to react, and everyone ran at the second shot," David Robertson said.
"When he shot the second time, that's when everybody ran," he said.
HPD said they got a description of the shooter from witnesses and were able to locate and arrest him.
Authorities said he is most likely a possible suspect.
Police added that the victim was taken to the hospital, where his condition was stabilized.
