Danish police say they are carrying out several raids across Copenhagen in connection with February’s deadly shooting at a free-speech seminar and the capital’s main synagogue.

Police spokesman Joergen Skov says the raids are part of “the continued investigation” into the February 14 and 15 attacks.

It wasn’t immediately clear whether any arrests have been made.

Omar El-Hussein killed a bystander outside the building where the seminar was held before spraying the entrance with 27 bullets.

Hours later, the 22-year-old El-Hussein fatally shot a Jewish guard outside the synagogue.

Five police officers were also wounded in the attacks.

El-Hussein was later killed in a police shootout.

Three men are already in custody suspected of assisting El-Hussein.
