TUNIS, Tunisia (AP) — A woman was arrested in Tunisia's capital Wednesday for allegedly attempting to run over police officers standing in front of a government building, Tunisian authorities said.

Three police officers were slightly injured when metal barriers knocked over by the woman's car fell on them, the North African country's Interior Ministry said.

The driver tried to flee but was immediately arrested, the ministry said. Authorities are investigating possible motives.

The ministry said later in a statement that a preliminary investigation indicated the attack had "no terrorist motive, but rather a criminal character."

The woman was said to be going through a "difficult psychic state" and allegedly wanted to draw attention to her situation, according to the ministry.

Last week, a police commander was stabbed to death in the neck by a suspected Islamic extremist near the headquarters of Tunisia's Parliament in Tunis. Another police officer was injured in that attack.

Islamic extremists have attacked soldiers and police in other regions of Tunisia, but it is rarer for them to target police in and around the capital.
