MIAMI (CBS4) – Miami-Dade Police say they have the woman who left a suspicious note in a piece of luggage, causing the evacuation of three concourses at Miami International Airport Tuesday afternoon.

Danisa Landaeta, 26, of Miami has been charged with Planting of a Hoax Bomb and Criminal Mischief. She is being held on $12,500 bond.

According to police, Landaeta placed a note in a friend’s bag with a drawing of a bomb and the word “BOOM” written on it. The friend, who was traveling to Venezuela, dropped the bag at the Transportation Security Agency checkpoint where the note was discovered. Police say Landaeta has confessed to writing the note.

Miami-Dade police spokesman Det. Roy Rutland said the incident started around 3 p.m. Tuesday when a TSA employee spotted the note in the  suitcase  near the Concourse F security screening area.

In addition to the evacuation of Concourses E, F, & G, airport spokesman Greg Chin said they also closed the upper and lower driving areas near Concourse F as a precaution.  Chopper 4 spotted hundreds of people outside of the terminals, many of them still holding their luggage.

Bomb detection K-9s were brought in, the swept the terminals but didn’t find anything.

Although the security checkpoint to Concourse F was closed, Chin says no flights were immediately canceled or delayed. Any passengers who had already passed through security were able to go to their gates.
