Shushan Baraby, suspected of involvement in last month's hit-and-run in Netanya in which three people were killed, reportedly attacked another inmate at Ayalon Prison on Wednesday.
Baraby allegedly kicked the unnamed prisoner's hands, which were put on the bars of his cell during an argument, causing a gash which required stitches.
The injured prisoner, who was taken to hospital for precautionary measures, filed assault charges against Baraby.
