A man stabbed multiple times in the torso was taken to the hospital, where he was pronounced dead, HPD said.
Houston police elaborated on the killing, saying that two men got into an altercation that escalated into violence. The man suspected of the stabbing remained at the scene as police were heading there. He was taken into custody.
They didn't immediately know what caused the fight or if the two men knew each other.
The stabbing marked the second-such killing on METRORail's Purple Line in a month. A 28-year-old woman was attacked at the Palm Center Station on Oct. 29.
Police don't believe there's any correlation between the two killings.

The investigation forced the suspension of the Purple Line. A bus shuttle was used to transport passengers, METRO said.
