“We arrested and charged Gaston Sichilima because he fired eight rounds of nine millimetres in the air,” Charity Katanga, the police commissioner for Northern Province, told AFP.
“He was charged with the offence of conduct likely to cause a breach of the peace after he fired in the air when we are still mourning our president.”
Sata, 77, died on Tuesday while undergoing treatment in London’s private King Edward VII hospital for an unspecified illness.
Sichilima had held various deputy ministerial positions in former president Rupiah Banda’s government.
He confessed to the charges and police have released him.
“We won’t take him to court,” Katanga said.
