The 74th Republic Day was celebrated with pomp and gaiety across West Bengal on Thursday amid tight security, with Governor CV Anand Bose presiding over an hour-long parade by the Army, the Navy, the Air Force, policemen and civilians, including school students.

Early in the day, a military helicopter showered rose petals on Red Road, the venue of official programme here, to greet the dignitaries, including Bose and Chief Minister Mamata Banerjee.
