"We are probing the case from all angles and nothing can be ruled out," Jalandhar Police Commissioner Arpit Shukla said replying to a query regarding the possibility of a terror outfit being involved behind the attack on Gagneja.
"We have got several leads on which we are working. It would not be proper to share them at this stage," he added.
"We have formed 10 teams to investigate the matter. Besides, the Special Investigation Team (SIT) is also camping at Jalandhar," he said.
Punjab DGP Suresh Arora had formed an SIT, led by ADGP-cum-Director, Bureau of Investigation, IPS Sahota, to crack the case.
On Saturday, senior RSS leader Brigadier (retired) Jagdish Gagneja was shot at by motorcycle-borne assailants at Jyoti Chowk in Jalandhar. He was seriously injured in the incident and is currently admitted to a hospital in Ludhiana.
