People in a number of offices and a school in Pori got panicky on Wednesday being informed by an anonymous phone-caller that there were bombs at the places.
Police said the bomb threat hampered normal activities at the offices and the authorities evacuated the school at downtown Pori.
The unknown caller told the school authorities that there was a bomb inside the school which might be exploded any time, prompting the authorities to make the school vacant immediately, sources said.
A number of offices also received similar threats which created panic among the people and disrupted normal activities.
Police said they had arrested an underage person in this connection, there were no major losses or casualties, and they were investigating the incident.
