A 12-bore gun allegedly used by the five men held in connection with the gang-rape of a Swiss woman in Madhya Pradesh, has been seized by police.
The weapon was reportedly used by the men to force the Swiss couple into submission, police said.
On Monday, the accused were produced before chief judicial magistrate R P Yadav at a local court in Datia.
The court sent them to police remand for a day. All the accused are in the 19-25 age group.
The arrested men were identified as Baba, Bhutha, Rampro, Gaza alias Brajesh, Vishnu Kanjar and Nitin Kanjar.
On Sunday night, police produced five of the accused before media persons and also showed a laptop, laptop charger, mobile phone and Rs 5,500 cash looted by the accused from the Swiss woman and her husband.
The Swiss couple - on a tour of India - were cycling through Datia when the 39-year-old woman was allegedly gang-raped by the accused at a forested area in Jhadia village, 8km from Datia town, on March 15.
Police have asked the couple, who are presently in police custody, to come and identify the accused.
The Swiss embassy has said the couple are ready to extend full cooperation to the investigators.
"While speaking to ambassador Linus von Castelmur the couple expressed their readiness to fully cooperate in the ongoing investigation and identification process. They will continue to stay in India for the moment," a Swiss embassy release stated.
Shocked Madhya Pradesh chief minister Shivraj Singh Chauhan said his government was devising a mechanism to monitor and track all foreign tourists.
"The state government would itself take care of foreign visitors and keep track of their journey in the state. An effective system would be put in place for their security and safety," Chauhan told media persons in the assembly.
On Monday, the state assembly witnessed chaotic scenes with the opposition Congress demanding the resignation of state home minister Uma Shankar Gupta.
