A 20-year-old Canadian man was detained, Sunday, on suspicion of carrying explosives onto a plane.
According to MSNBC, the 273 passengers were told that the plane landed due to technical issues in Sweden on its way to Pakistan from Canada.
On CNN.com, it was reported that the man was released with not enough concrete evidence against him. He also did not know why he was involved in the situation and why he was being questioned.
The Star Tribune reports that the call was made from an unidentified woman that may have had an "ax to grind" with the man. If the woman is found she may be charged with public mischief.
