The city police have arrested Sebastian (33), brother of businessman Arulanandam, a prime suspect in the Loyola Matriculation assault case, on Wednesday.
On Tuesday, Mohideen (33), who worked in Arulanandam’s company, was nabbed from a hideout in the city.
A senior police officer said a total of 38 persons have been arrested for the alleged assault.
Bhaskar, a physical education instructor at the school, was allegedly assaulted by Arulanandam’s men after the teacher reportedly subjected the businessman’s son to corporal punishment on November 20.
