Restrictions began Tuesday in some Bamenda areas to facilitate search and rescue operations for kidnapped school children, according to local authorities.
On Monday, the army used military police and helicopters to find children.
Although no one has taken responsibility for abducting students, the authorities have not ruled out the participation of fragmentary fighters who are conducting a war in the English-speaking provinces of Cameroon.
Several divisions refused to take part in the kidnapping.
He described Monday's abduction as a "massive distraction tactic" by President Paul Biya's government to divert international and local attention from the inauguration of the President.
He said members of the separatist group had a mandate to look for communities in the area to reveal the hiding place of the kidnappers.
CNN is not in a position to reach the government immediately for comments on Tanku's allegations.
He called for peace in the turbulent English speaking regions of the country during his inauguration in the country's parliament.
Seven students and chief teacher were kidnapped in September by armed detainees from their school in Bafut, northwest of the country, according to Amnesty International.
The hostages were "tortured and seriously injured" by their abductors before their release, the human rights group said.
Rights groups accused the 85-year-old leader of presiding over a barbarous regime infringed by human rights abuses, particularly in residents and armed detached in Cameroon's English-speaking provinces.
Armed separatists also face charges of killing and kidnapping civilians and soldiers.
English speaking crisis
The instability in Cameroon's English-speaking provinces is nothing new.
Cameroon in the northwestern and southwestern province accounts for about 20% of the country's population, but they say the government that spoke mainly from France was marginalized.
The English-speaking problem, as it is sometimes called, is a legacy of West African colonial past. Germany claimed the region before the First World War, but after the loss of war the lands were divided and "given" to the English and French governments.
The nation that became Cameroon was an awkward merger of these two colonies.
The current turmoil escalated in late 2016 when lawyers, teachers and students started a strike and held street protests about what they said was continuing discrimination against Anglo-French.
Strikes and boycotts led to serious repression by the police and soldiers, say groups like Amnesty International and Human Rights Watch. These groups and local activists say that many villages have been cut and that politicians were killed by government action.
The government claims that it is only trying to maintain law and order. In this spiral of violence, armed detainees have formed and killed many troops and police in subsequent battles – often using tapping and execution tactics.
Some observers say the President is not in touch with the situation on the ground. The President spends much of his time outside the country.
Biya condemned "acts of violence", regardless of their sources.
