Amritsar grenade attack: One accused arrested, searches for another is on: Amarinder

One person has been arrested in connection with the grenade attack in Amritsar that left three people dead and over 20 injured on Sunday, Punjab Chief Minister Amarinder Singh said on Wednesday.

"One Bikramjit Singh has been arrested and searches for another accused, Avtar Singh, is on," Amarinder told the media here.

The chief minister also showed pictures of the two accused and assured that the second person would be nabbed soon.

Pakistan's Inter-Services Intelligence is quite active in fomenting trouble in Punjab and the grenade attack in Amritsar was a pure act of terrorism, Singh said.

Three people including a preacher were killed and over 20 injured when two-motorcycle borne men threw a grenade on a religious congregation on the outskirts of Amritsar on Sunday, an incident which police are treating as a "terrorist act".

The incident had taken place inside the Nirankari Bhawan's prayer hall at Adliwal village near Amritsar's Rajasansi.
