Maneka Gambhir, the sister-in-law of TMC MP Abhishek Banerjee, left the Enforcement Directorate (ED) office here on Monday evening, seven hours after she appeared before it for questioning in connection with a money laundering case.

Gambhir, who entered the ED office at CGO complex in Salt Lake at 12.40 pm, left at 7.40 pm.

She did not take questions from waiting media persons.

The ED had sent fresh summons to Gambhir after it was found that the agency "erroneously" issued her a notice for appearance at 12:30 am instead of 12:30 pm on Monday, official sources said.

She was asked to appear before the agency's officers by 2 pm in the fresh summons.

Gambhir was handed over the summons to appear at the ED office here on Monday "at 12:30 am by agency officials at the Kolkata airport on September 10" in connection with an alleged coal scam case.

She reached the ED office in Salt Lake area around the stipulated time given on the summons but as it was an erroneous date issued inadvertently, she found the office closed and returned after clicking some pictures, the sources said.

The TMC MP's sister-in-law was accompanied by her lawyer when she visited the ED office at the time stipulated earlier.

The sources said the midnight time printed on the earlier summons was a "typographical error".

The Calcutta High Court on August 30 directed the ED to question Gambhir at its regional office in Kolkata and not Delhi. It asked the agency also not to take coercive steps against her till the next date of hearing.

Gambhir had challenged the ED summons that asked her to appear before it in Delhi on September 5 and had sought direction from the court to the agency to allow her to appear before it in Kolkata.

She filed a contempt petition before the Calcutta High Court on Monday claiming that the ED did not allow her to travel outside India despite no such restriction imposed on her in its order.

The ED had earlier questioned Banerjee and his wife Rujira.
