The meeting was held on the direction of Speaker Yoganand Shastri after MLAs demand police protection citing increased "threat perception" while having to deal with difficult situations in public interest.
Gupta met Dikshit hours after MLA Bharat Singh was shot at by unidentified men at his office in southwest Delhi today.
Yesterday in Delhi Assembly, an extortion call to MLA Jaswant Rana's son had prompted other legislators to seek enhanced protection.
The strong demand by the legislators came after senior MLA Jaswant Rana said in the assembly that his son received a call last week from an unknown person demanding Rs 50 lakh.
Following Rana's demand for adequate security, a number of Congress MLAs also joined him in seeking police protection in the wake of "increased threat perception" and to carry out developmental works "fearlessly".
Dikshit had said security of the MLAs was of "paramount importance" and the incident involving the legislator is being taken up with the police seriously.
As number of Congress MLAs demanded "adequate security" for the legislators, Speaker Yoganand Shastri issued a direction to call Police Commissioner B K Gupta to the House to convey concerns of the MLAs.
