Rio de Janeiro, Aug 8 (IANS/EFE): Two people have been arrested for their alleged involvement in the on-air killing of a Brazilian radio host, officials said.

The suspects were apprehended on Friday at a home near Camocim town in the northeastern state of Ceara where radio host Gleydson Carvalho was murdered.

Two other suspects, who ran from the residence when police arrived and have been identified as the purported assailants, are currently being tracked down by the authorities.

"We arrested two people at a home where we found the weapons used in the crime and the clothes worn by the gunmen, as well as a photograph of the radio host, and we've called for the arrest of the other two," Camocim's chief of police Herbert Ponte e Silva said.

The two suspects in custody have provided details about how the crime was planned and executed, he said.

"We're now searching for the two gunmen, who fled to a wooded area unarmed, without transportation and barefoot," he said, adding that the authorities were trying to determine who hired the killers.

Carvalho, who had accused many local politicians of corruption and received numerous death threats on his Facebook page, was shot on Thursday at the studio of Radio Liberdade FM and died en route to a hospital.
