UPDATE (Jan. 15, 11 p.m.):

An LSU news release said a second armed robbery charge was placed on Tyzell Duncan on Monday. Both armed robberies are under investigation regarding other suspects.


ORIGINAL STORY:

LSU police arrested a man on Saturday suspected in a Wednesday on-campus robbery after Baton Rouge police arrested him in an unrelated incident, according to arrest reports.

Tyzell Duncan, 18, was questioned Saturday by LSU investigators following his arrest by Baton Rouge police and a tip that identified him as one of the robbers, according to LSU spokesman Ernie Ballard and LSU police reports. Ballard said Duncan does not attend school or work at LSU.

Duncan was first arrested Saturday afternoon after a woman called Baton Rouge police to report that three people broke a window at her home in the 200 block of Delphine Street while trying to get inside, according to a Baton Rouge police arrest report. The woman had briefly let the two men and one woman stay at her home.

When police arrived at the woman's home in response to the call, the three people were gone, but officers found Duncan three blocks away, according to the report. Duncan tried to run away and fight officers, but as they were handcuffing him, a revolver fell out of his jacket.

Duncan denied being at the woman's house, but the woman identified him as one of the people who broke her window, police said. The 18 year old also had an active warrant out of Ascension Parish.

Duncan, of 146 South 21st St., Baton Rouge, was booked in Parish Prison on criminal damage to property, illegal possession of a stolen firearm, illegal carrying of a weapon and resisting an officer. It was not immediately clear if the other two people involved in that incident have been arrested.

LSU officials released photos earlier this week of three people involved in the Wednesday robbery, which happened around 12:30 a.m. near the northwest side of Kirby Smith Hall. The photos depicted three people, including one in a clown hoodie, standing near a gate.

LSU police said in an arrest report for Duncan that they received two separate tips in response to the photos: one that identified all three people and another that just identified the person in the clown hoodie.

After Baton Rouge police detained Duncan, he told LSU police that he "hangs around" with the other two people identified in the tip and that the other two people take turns wearing the clown hoodie, according to Duncan's arrest report.

When Baton Rouge police arrested Duncan, he had a small silver revolver handgun, which matched the description of the gun used in the armed robbery, LSU police said. Duncan denied participating in the robbery, but said one of the other people "uses his gun," according to the report.

Police said Duncan was wearing a dark sweater that matched one in the photos and that he "displayed several clues of deception and changed his story several times," in the LSU police report.

Duncan was booked in Parish Prison on armed robbery in the LSU incident.

The incident was the second armed robbery that happened on campus in two days. A crime alert went out to students and employees around 4:30 a.m. Tuesday saying that a robbery happened on Highland Road near Dalrymple Drive.

Ballard said both cases are still under investigation.
