All are suspected of preparation for murder and one of the men is suspected of murder. All three are arrested on probable cause, the higher degree of suspicion.
The men were detained in connection with the regional task force carrying out three house searches on Saturday morning.
It was during the night of Sunday, October 8, that a 25-year-old man was found shot to death outside in the Araby district, after residents in the area alerted the police about loud explosions.
No one has previously been detained in the case.
Correction: In an earlier version of the article, it was described how three people were arrested on suspicion of murder. Correct task is a person.
