Last week, President Magufuli promoted Mr Haji to be the CP from the rank of Deputy Commissioner of Police (DCP).
According to press statement released by the State House and signed by the presidential communication director, Mr Gerson Msigwa, CP Haji replaces Mr Hamad Omar Makame who has retired.
Speaking at the event, IGP Sirro congratulated the new CP and reminded him of a huge task he faces to maintain security in Zanzibar.
"There are many claims that we are slow in investigation and our colleagues are corrupt. We need to instill discipline and ensure officers failing to abide by the rules and regulations are taken to task accordingly,” he said.
The IGP said they were tasked to fight corruption and curb drug trafficking with the new zeal, hinting that Mr Haji may succeed him if performs his duties in accordance with the principles governing the police force.
For his part, leader’s secretary at the Ethics Secretariat of Public Service, Mr John Kaole stressed on the need for the police officers to abide by codes of ethics and that discipline should be a top priority.
Mr Haji thanked President Magufuli for trust he extended to him and the IGP for officiating his swearing in, promising that he will discharge his duties according to the rules, regulations, laws and principles.
Before promotion, Mr Haji served as the Zanzibar Chief Executive Officer of the Police Force.
