An Antioch man wanted by police after he allegedly stabbed his pregnant girlfriend and a family dog has been arrested, police said Monday.

Police caught up to 18-year-old Johnny Madden around 5:53 p.m. Friday, Antioch police Sgt. Tony Morefield said. Madden tried to run from police after they approached him in the 2900 block of Delta Fair Boulevard, but officers caught him after a brief chase, Morefield said.

The charges against Madden will be determined by the Contra Costa County Attorney's Office, police said. He was being held on suspicion of false imprisonment with violence; use of a deadly weapon that was not a firearm; inflicting corporal punishment on a spouse or cohabitant; and cruelty to an animal.

Madden had been on the run since the stabbing Wednesday morning of a 16-year-old girl who is pregnant with twins, police said. The girl, who police say is Madden's girlfriend, was not injured seriously, and her babies also are OK, police said.

Also stabbed was a 6-month-old shepherd puppy. The dog needed emergency surgery and had part of his liver removed, police said.

Police said Madden fled from a home in the 2200 block of Hamlin Drive after the stabbings, which occurred around 10:35 a.m. Wednesday.

Over several hours before the stabbing, several postings on a Facebook page belonging to Madden had references to drinking heavily and getting "turnt up," slang for getting high and drunk. The postings began at 1 a.m. Wednesday and continued into the morning hours.

"I stay high no lie i be drinkin," one posting read. "Shot after shot like a bottle is a fully auto," read another.

Madden was taken to the County Jail in Martinez and was being held in lieu of $150,000 bail.
