MEXICO CITY (AP) — Mexican authorities said they detained seven more federal police officers Thursday in the northern border city of Matamoros in connection with an extortion investigation.
A statement from the National Security Commission said the seven were taken into custody at the Matamoros airport.
On Saturday, Mexican officials said soldiers and marines had detained 14 other federal police officers in Matamoros for kidnapping a businessman and demanding a $2 million (31 million peso) ransom. One was later released.
Thursday's statement did not say if the latest detentions were related to that case. But Federal Police Commissioner Enrique Galindo tweeted later that a total of 20 officers had been detained for the kidnapping.
Matamoros lies across the Rio Grande from Brownsville, Texas.
