For the second time in less than a month, racist graffiti targeting Chinese people has been found scrawled on the walls of a shopping centre in Richmond, B.C.

The anti-Chinese messages were found Monday morning in the parkade staircase of the Richmond Public Market. Police say they are looking for help from the public to identify possible suspects.

In July, two teens were arrested in connection with racist messages found in a stairwell at the Empire Centre. Those messages also targeted Chinese people, as well as women and the police.
