Funding call
To mark the anniversary, Mr Okiro paraded a crack squad of about 50 police officers in front of reporters on Thursday at police headquarters in the capital, Abuja.

He said they were responsible for the crackdown on crime mainly witnessed in north-eastern Nigeria.

Apolice spokesman told the BBC that 62 officers had also lost their lives when taking on suspected armed robbers.

As part of his anti-corruption crusade, Mr Okiro said 28 police officers caught collecting bribes on the roads had been dismissed during his time in office.

Speaking to a parliamentary committee on Wednesday, he called for $26m of outstanding state funding to be paid to the police.

He said the force was in dire need of accommodation for its more than 360,000 personnel, Nigeria's Daily Trust newspaper reports.
