Ch Supt Alex Murray said the man they arrested was of Somalian descent and that a "sizeable knife" had been used in the attack.
A man who was praying at the time has claimed that the suspect, who regularly attended the mosque, was involved in a heated argument moments before the attack.
The eye-witness, who asked not to be named, said: 'The man, who is from Somalia, had been at the mosque for the last prayer of the day before the men started arguing.
'It turned violent quite quickly. Some people tried to get the man to calm down and asked him to leave.
'But next thing he had stabbed the three men and everybody just panicked - it was an extremely scary thing to witness. This is a place of worship and respect - not a battlefield.'
