Ray Zammit was appointed assistant commissioner and Carmelo Magri, superintendent, this afternoon.
Home Affairs Minister Carmelo Mifsud Bonnici said during the ceremony that the people considered each crime to be an important one which deserved to be investigated.
The force should follow each report they received from the public - a main source of information, because victims of crime had the right to justice. This would lead to more trust in the force.
Dr Mifsud Bonnici said the criminality rate continued to go down every year for the past four years.
Police work was bearing results and this could be seen in the increase of 100 people in the prison population since the beginning of the year, the record number of people arraigned in the same period and the nearly half a tonne of drugs hauled.
He said that six assistant commissioners and 12 superintendents were appointed during this legislature.
