LOS ANGELES - The city of Los Angeles is offering 75,000 US dollars in reward for information over the killing of two Chinese graduate students, local media reported Tuesday.

The reward was announced at 10 am by Los Angeles City Councilman Bernard Parks, according to local television channel KTLA.

The new reward followed a 125,000 US dollars pledge announced by the University of Southern California last Friday for information leading to the arrest and conviction of the suspect.
