Nine of those arrested were described as operatives of the Muslim Brotherhood, which has been protesting what they say was a military coup that ousted the democratically elected Morsi.
At least 221 were injured, the Health Ministry said Saturday.
Ahram Online noted the ministry did specify how many of the casualties were demonstrators and how many were police officers.
Police told Ahram Online two suspects picked up in Sohag were delivering bags of food to low-income neighborhoods to entice residents to join the anti-government protest.
The report said the protests drew large crowds, but not as large as the Muslim Brotherhood had predicted.
