Purohit, who was arrested by the Nashik crime branch on Tuesday, was produced before Joint Civil Judge V V Joshi where police custody was sought.
The case against Purohit had been registered by Pune resident Shirish Date in the Sarkarwada police station in Nashik on November 16.
Date, a family friend of Purohit, stated in his complaint that a license for a gun had been obtained for him by the army officer.
The Pune resident claimed fake documents showing him as a resident of the military camp in Devlali were used to obtain the arms license for him.
The Nashik police took custody of Purohit on Monday after moving an application before the special MCOCA court conducting the trial in the Malegaon blast case.
Earlier, the Pune ATS had taken custody of Purohit for providing an arms license using fake documents to Date's relative.
Another accused in the Malegaon blast, Sudhakar Chaturvedi, is also alleged to have obtained a country-made revolver from Purohit.
Eleven persons, including Purohit, have been arrested so far for their alleged involvement in carrying out the September 29 blast in Malegaon which left six dead and over 80 injured.
