"This "hate crime" is a repercussion of the California shooting," said Sikh community leaders.
The Gurdwara vandalised in Los Angeles suburbs on Sunday morning is being investigated by local law enforcement agencies.
"We are concerned about the safety and security of our community members. We are of the opinion that this is a hate crime and that this is a direct result of a possible backlash from the San Bernardino killings," said Inderjot Singh, president of Sikh Gurdwara in Buena Park, a suburb of Los Angeles.
"The Gurdwara was vandalized during Sunday early hours and a hateful graffiti was seen on the walls of the Gurdwara and also a truck parked in the parking lot. The graffiti included the phrase, "F@#k ISIS," and the words "Islam" and other reference of gangs," Washington-based Sikh Council on Religion and Education (SCORE) said in a statement.
The Gurdwara is attended by over 800 community members on a weekly basis. The White House, which was informed about the incident, has forwarded the incident to the Department of Homeland Security to investigate.
