Egypt's interior ministry has denied that a police officer was killed in a blast in North Sinai, Al-Ahram's Arabic news website reported.
News circulated following the blast that an officer was killed and 10 security personnel injured.
An IED exploded as an armoured vehicle, carrying the security personnel, passed near it on the Al-Arish ring-road.
However, a security source from the ministry told Al-Ahram that no one was killed.
This leaves 11 security personnel, one officer and 10 conscripts, injured, according to Reuters' news website Aswat Masriya.
The victims have been transferred to hospital.
Egypt's army has been fighting an Islamic insurgency in the violence ridden northern part of the peninsula, killing dozens in the past year.
Jihadist groups have used IEDs, among other methods, to attack security forces on a number of occasions.
Last week, 11 security personnel were killed and four others injured, also in an IED attack in the North Sinai city of Sheikh Zuweid.
