In response to three recent shootings, police in Rotterdam-IJsselmonde have warned residents to exercise caution when going outside, particularly at night. Authorities have found bullet casings linked to an earlier shooting that resulted in a fatality. The police believe a single shooter is responsible for the incidents and have released a new photo of the suspect, now identified as having a darker skin tone. A reward of 30,000 euros is being offered for information that leads to the suspect’s arrest.
