Prosecutor Pär Andersson is wordy about the arrest:

- He has been arrested on suspicion of assisting in the murder and is likely to be arrested in the middle of the week, he says.

More suspect

According to Sydsvenskan who was the first to tell about the arrest, the man is 23 years old, but Pär Andersson does not want to comment on the arrested man's age.

Karolin Hakim was shot to death while carrying her newborn baby in her arms. Two people have previously been suspected of involvement in the murder.

- It's none of the previously arrested people, says Pär Andersson.

- I choose not to say more than that right now.
