Many houses were raided in Istanbul on Tuesday morning. At least 15 people were detained, including members of the Workers' Party of Turkey (TIP), Revolutionary Youth, Federation of Socialist Assemblies, Social Freedom Party (TÖP), Labor Movement Party (EHP), Socialist Laborers Party (SEP) and Socialist Assemblies Initiative (SMI).

Those detained were taken to the Istanbul Police Department in Fatih.

It was noted that the reason for the detentions was the alleged resistance to the police barricades on the way from Saraçhane to Taksim on 1 May.

Sources said that the number of detainees may increase.
