Philippine President Rodrigo Duterte allegedly once shot dead a justice department agent with an Uzi submachine gun while serving as mayor of Davao.
The allegation was made by Edgar Matobato, a self-confessed former death squad member, before a Senate inquiry on extra-judicial killings.
Mr Duterte, he alleged, ordered him and others to kill about 1,000 criminals or political rivals over a 25-year period.
However a spokesman for Mr Duterte denied the allegations.
However the presidential spokesman Martin Andanar denied the allegations stressing that investigations into the president’s time as mayor had gone nowhere
