NAIROBI, Feb. 21 (Xinhua) -- Four Kenyan police officers were being interrogated Wednesday after being arrested over human smuggling claims.

According to the security report, the four police officers were arrested Tuesday, and 37 Ethiopians were rescued after they were found in a house on the outskirts of Nairobi, the Kenyan capital.

According to police, three of the officers are said to have been operating outside their jurisdiction without the knowledge of their commanders.

The sting operation, conducted by detectives from the Transnational Organized Crime Unit of the Directorate of Criminal Investigations (DCI), caught the officers unaware as two of them attempted to escape in vain.

According to the report, an extended search was conducted at the adjacent plot after two men were seen jumping, and it was established that the two were police officers. Both were injured on the ankle in their futile attempts to escape and grounded.

Both were armed with Beretta and Ceska pistols. The weapons were later confiscated from them.

While the detectives were still at the scene, two other officers also arrived at the scene while accompanied by two other foreigners in a vehicle.

Both officers, who were armed, had arrested two other aliens who had been handcuffed, police said, adding that the officers were both detained.

The owner of the house was yet to be traced, the police said.

The incident comes amid police operations on suspected smuggling incidents.
