Detroit police have one person in custody in connection with the stabbing of a 14-year-old boy on a city bus.
DeJon McGhee was stabbed in the chest Wednesday evening after trying to break up an argument between two other riders near Dexter Avenue and Lawrence Street.
Witnesses said the other riders, two men, starting talk about Martin Luther King Jr. and one of them claimed to have killed the civil rights leader.
When McGhee stepped in, his classmates said the man got upset.
"He called him names, he called him a (expletive). Then he told him that he killed MLK, something like that," said Precious Jones, one of the students who was on the bus. "Everybody kind of got upset on the bus."
Police said DeJon was defending himself when he punched the man in the nose. The man then took out a knife and stabbed him.
