Replying to a question, Ikram said the couple deposited the arms at the police station willingly following the GD.
He said they will start an investigation into the complaint of Jahanara after getting permission from the court.
"We've already sought permission from the court to carry out the investigation, but we're yet to get the court order."
On Thursday evening, Jahanara registered the GD against her beleaguered husband with the same police station accusing him of torturing and issuing her a death threat.
She called 999, the National Emergency Service, seeking cooperation from the police to save her from her husband's torture.
As police visited her residence, Jahanara told law enforcers that she has been subjected to physical and mental torture by her husband and even he threatened to kill her.
On 7 December last, Murad Hassan resigned from the cabinet following the instruction of prime minister Sheikh Hasina for his offensive and indecent remarks on women.
After the resignation from the cabinet, Murad had left the country in his desperate bid to hide amid widespread criticism at home, but his attempt to stay abroad went in vain as he had to get back home having failed to enter Canada and the UAE.
