Sgt. Randy Finchman says police have spoken to the man, but decided not to lay charges.
"In laying a charge, investigators would need to establish that a criminal offence took place, laying a charge was in the public interest and that there was a substantial likelihood of a conviction.
"In this case, it was determined that all three criteria had not been established," said Finchman in the statement release on Tuesday morning.
Instead the man was advised his action were inappropriate.
"The man has been made aware of the cultural significance of the memorial and that his alleged activity in and around the memorial was inappropriate and insensitive to the South Asian community."
Memorial erected in 2012
On May 23, 1914, the Japanese charter ship Komagata Maru arrived in Vancouver harbour with 376 immigrants from India. Canadian immigration officials refused to let the passengers disembark, using the continuous journey regulation which required migrants to arrive in Canada directly from their country of origin.
The ship was forced to anchor in the harbour, where it stayed for two months before finally returning to Calcutta, with all but 22 of the original passengers aboard. A riot broke out upon the ship's return to India, in which 20 passengers were killed.
The memorial was erected in 2012 in Vancouver's Coal Harbour. In 2008 B.C. apologized formally for the incident.
