The BJP’s Khardah bypoll candidate, Joy Saha, was allegedly attacked, along with others, by suspected Trinamul supporters during a clash over putting up banners near Girja More in Khardah on Sunday night.

Allegedly, ruling party supporters forced BJP supporters to leave. Three injured BJP supporters are in hospital.

Saha has lodged a complaint with Khardah police. But no one was arrested in this connection till Monday night.

Saha termed the incident as a planned attack to kill him and terrorise party workers. The party has told the Election Commission about the attack.

Police and local sources said trouble broke out at Girja More around 10pm on Sunday when some Trinamul supporters allegedly removed BJP banners and set them on fire.

“Our party workers were putting up banners when a group of 20 Trinamul activists backed by goons attacked them. They removed our banners, flags and buntings and began beating our people. I rushed to the spot,” Saha said. “I was checking the gutted flex when they began to hurl stones at me and ransacked my car. I alerted police, but they were mute spectators.”

Local Trinamul leaders denied the charge. “None of our party workers was involved. I learnt it was a fallout of BJP’s internal bickering,” a Trinamul leader in Khardah said.
