Kolkata/UNI: Seven primary teachers in the West Bengal government-aided schools accused of getting jobs against cash (bribe) on Wednesday appeared before the CBI's investigation officials at its Nizam Palace office in the city, official sources said.

The CBI summons of the seven teachers from Bankura district happened barely two days after four such teachers were arrested by a special court order in the city.

They were arrested by the court order when they were produced and interrogated by the judge of the CBI court in Alipur, south Kolkata.

The court was also dissatisfied with the central investigation agency for producing them as the witnesses of the West Bengal
School Service Commission scam in which minister Partha Chatterjee, some legislators and many present and former government officials have been arrested.

The four primary school teachers, who were arrested on Monday after they were summoned to the CBI court in Alipore, allegedly paid at least Rs 5 lakh each to now expelled Trinamool Congress youth wing leader Kuntal Ghosh to secure jobs, the court was told.

Crores of rupees were taken from the "unqualified candidates" for jobs in the government-aided primary schools denying the qualified candidates.

Jailed Kuntal Ghosh and small-time businessman Tapas Mondal were close associates of jailed TMC MLA and West Bengal Board of Primary Education (WBBPE) former president Manik Bhattacharya, the Central Bureau of Investigation alleged.
