The new governor, Mukthar Yero, also declared Monday (today) as a work-free day.
In a state broadcast on Sunday, Yero said the remains of Yakowa would arrive the state on Monday.
Meanwhile, President of the Nigeria Labour Congress, Mr. Abdulwahed Omar, has called on the Federal Government to institute a high-powered probe into the helicopter crash that killed Yakowa and a former National Security Adviser, Mr. Andrew Azazi.
The NLC also called for a thorough check of the Presidential fleet, private jets and others in the country.
Omar said the crash indicated those entrusted in ensuring aviation safety had not done enough.
NLC said, â€œWhile we condole with the families of those who died in this crash, we urge the Federal Government to institute a high powered probe into the cause of this crash.â€
