Turkish authorities say a bomb placed on a bicycle has exploded at a bus stop during rush hour in Istanbul, injuring seven people.
None of those injured were in a critical condition.
The explosion occurred on May 26 near a shopping mall and a police training school.
Officials said there was no major damage, suggesting the bomb was relatively small.
Police sealed off the area as investigators searched for clues. There was no immediate claim of responsibility.
Kurdish rebels are fighting for autonomy in southeastern Turkey and have carried out bomb attacks in Istanbul in the past.
Their jailed leader, Abdullah Ocalan, has warned of more violence if their demands for negotiations are not met after elections on June 12.
