An Egyptian policeman was shot dead by unidentified gunmen in the North Sinai city of Arish on Thursday, a security source said.
No group has claimed responsibility for the attack.
Egyptian authorities have yet to comment on the incident.
On Wednesday, a soldier was shot dead by unidentified gunmen in central Sinai.
Egypt's Sinai Peninsula has witnessed mounting violence against police and army personnel since the July 3 ouster of Mohamed Morsi, the country's first freely-elected president, by the powerful military.
Within recent months, scores of policemen and soldiers have been killed in dozens of attacks by unidentified gunmen, especially in the peninsula's volatile northeastern quadrant.
The Egyptian army is currently carrying out what military experts are calling the largest military operation on the peninsula since Egypt's 1973 war with Israel with the stated aim of combating "militancy and terrorism."
