Jalandhar: A bomb threat email to five prominent temples in Punjab on Thursday triggered a security alert.
The email also threatened blasts at some government establishments, officials said.
According to officials, the threat email - which comes two days ahead of the anniversary of Operation Blue Star - contained highly inflammatory references to the controversial military operation conducted in June 1984 to flush out the militants from the Golden Temple.
In Jalandhar, police personnel carried out a check at Devi Talab Mandir, but no suspicious object or explosive material was found, police said.
While it appears to be a hoax threat intended to spread panic, no risk can be taken and security has been tightened, police said.
Cyber teams are probing the origin of the email, they said, adding that further investigation into the matter is underway.

The fresh scare comes close on the heels of similar threats to multiple places in Punjab and Haryana in the past few weeks, which were later proved to be hoax.
Thursday's bomb threat comes amid heightened security arrangements in view of the anniversary of Operation Blue Star.
