The Honduran police on Tuesday detained a soldier accused of killing a follower of ousted Honduran President Manuel Zelaya along the border with Nicaragua.
The president's follower was shot dead on Sunday when he tried to pass a military checkpoint on a car in Las Manos, 120 km east of Tegucigalpa, while the curfew was still valid.
The guard at the check point opened fire at the car after it did not pull up despite the guard's order.
The soldier, named Fredy Flores, will be brought before court on Tuesday, police spokesman Orlin Cerrato said.
The Honduran interim government has lifted a dusk-to-dawn curfew for most of the country. But the curfew was still in place along the border with Nicaragua where many Zelaya's supporters have gathered.
