Israel Police on Tuesday arrested four suspects over the shooting murder of a 20-year-old man in Bat Yam a day earlier.

Mor Algrabli was sitting in his car when he was shot in broad daylight by an assailant on a motorcycle. A friend sitting next to him was seriously injured in the incident.

Algrabli had a police record, and was allegedly involved in drug and property crimes, in addition to possible gray market dealings. He was not thought to be a major criminal figure.

He had also played soccer with the Holon soccer club that his father, David, coached and managed.

According to witnesses, a motorcycle carrying two people stopped a few meters from Algrabli's car, and the passenger pulled out an Uzi submachine gun from under his coat and fired several shots at Algrabli.

After Algrabli was hit, his friend reportedly managed to get out of the car, and was shot in the abdomen by the gunman. After the shooting, police set up road blocks in an attempt to catch the gunman. The search was later widened, and police helicopters were brought in.

The Ayalon district of the Israel Police set up a special team to investigate the murder. They decided not to transfer the case to police headquarters in Tel Aviv, because they believe the murder involves a dispute between local criminals.

A gag order has been issued regarding details of the investigation. However, police believe the case involves an "honor" killing in connection with a settling of accounts between local criminals.

The murder occurred near the home where Algrabli and his family had recently moved. When his mother came out of the house after the shooting, she collapsed at the scene.
