A man who D.C. police said beat his girlfriend and then put her 4-month-old child outside without supervision has eluded arrest, even though he is being monitored electronically while awaiting trial on a gun charge, according to authorities.

Police were searching for the 24-year-old Maryland man Tuesday. The alleged assault occurred over the weekend. Authorities said his court-assigned GPS ankle bracelet is no longer working, but they would not say whether he removed it or let the battery die.

Cliff Keenan, director of the District’s Pretrial Services Agency, said that the monitoring devices “are not infallible.” They are not monitored in real time, but rather are designed as another check to ensure that the person being monitored has adhered to restrictions, such as curfews and limits on places to visit.

D.C. police said the incident occurred in an apartment in the 700 block of Brandywine Street SE in the Washington Highlands neighborhood. Police said the victim was beaten in the face until she passed out Friday, and was then kept from calling 911 until she managed to run from the house Sunday and contact police. Police said the man put the couple’s 4-month-old girl in a car seat and placed it outside the apartment, where authorities found the child when they arrived. But the man was not there.

The man, who The Washington Post is not naming because he has not been charged in the domestic incident, had been freed from jail in July after his arrest on charges of possession a handgun and unlawful possession of ammunition.

Court papers say police apprehended the man in Southeast Washington with a .40-caliber Glock pistol. Police said the gun was loaded with 10 rounds of ammunition.

The suspect’s attorney did not return a call seeking comment.
