Defence spokesman Chris Olukolade said the helicopter left on a training mission at about 9:30 am (1400 IST) from the airport in Yola, capital of Adamawa state, which is under a state of emergency because of Boko Haram's violent uprising.
The pilot executed "a controlled forced landing four minutes after take-off", Olukolade said in a statement. "There is no casualty recorded."
But the military's account differed from that of witnesses in the town of Damare, just outside Yola.
He said there were five foreigners on board.
That report was supported by a senior security source in Adamawa who requested anonymity. The source identified some of the passengers as "oyinbos" -- slang for white person.
There was no immediate indication on the identity of the purported foreigners.
According to Alimu, four other helicopters were dispatched to the crash site and the five foreigners were whisked away. He said the helicopter's cargo was loaded into military vans.
Nigeria's military has suffered a series of air crashes in the northeast since it launched an offensive in the region against Boko Haram in May of last year.
The Islamists have claimed to have shot down a number of aircraft, including a Nigerian air force jet that went missing in September, again on a mission out of Yola airport.
But those claims have been dismissed by the military and not supported by witness accounts.
