The online edition of the newspaper '20 Minutes' reported that the 49-year-old offered no resistance as he was arrested.

The man was said to have fled on Wednesday afternoon after having shot his wife and son in the block of flats where the family had been living in Payerne for a little over a month.

According to the website, the two bodies were found on the floor of the family's flat.

After police were called, they evacuated all tenants from the building and surrounded it in an attempt to find the killer, before realising that he was no longer inside it.

According to residents, frequent arguments could be heard from the family's flat.
