A stampede-like situation was witnessed after about 800 persons turned up for walk-in interviews held by a firm for 40 vacancies in Ankleshwar in Gujarat's Bharuch district, an official has said.
Party's state unit chiefs of Delhi, Uttar Pradesh and Gujarat were also detained along with the workers during the protests.
According to officers who were part of the probe, detecting a crime that was committed with proper planning, involving different modules working separately for a common cause, was a challenging task.
A total of 19 legislators from the opposition Congress and Aam Aadmi Party were suspended from the Gujarat assembly for a day on Wednesday after they shouted slogans against the Bharatiya Janata Party government before walking out of the House over the issue of a fake trainee PSI found undergoing training at a state-run police training academy.
