He is the 10th AAI employee to be arrested.
Aji Kumar was arrested on the same charge that the nine AAI officials were arrested earlier, Kondotty Circle Inspector B Santosh, the Investigating Officer in the cases, told PTI.
Police said Kumar had been hospitalised on June 10 after he sustained some injuries in the clash. He was discharged today and was arrested from the hospital itself, they said.
Meanwhile four CISF jawans, arrested yesterday, were produced before Chief Judicial Magistrate court at Manjeri (Malappuram district) today and and remanded to 14 days judicial custody, they said.
A dispute over a CISF personnel insisting that an official of AAI's Fire Force department undergo security clearance had led to a verbal duel between the two. In the ensuing melee, the jawan received fatal gunshot injuries.
After the violence, the airport had been temporarily closed and flights were diverted to Nedumbassery airport in Kochi on the night of June 10. Flight operations resumed the next day.
Police had on Saturday registered a case against the SI and 100 CISF personnel in connection with the clash.
