Indian documentary filmmaker Vijay Kumar, arrested in Houston for allegedly carrying "jihadist" literature and brass knuckles in his checked baggage, will remain behind bars without bail but can leave "voluntarily" if his case is resolved within 120 days.

Kumar, 40, who relied on the US Department of Homeland Security's travel rules to carry the items prohibited in Texas, was on Thursday denied bail by a Houston judge and ordered to stay in jail on federal immigration charges until allegations against him are resolved, Houston Chronicle reported.
