Santa Ana Police Answer Flurry of Crime : Law enforcement: Officers respond to a carjacking, a fight and a man firing his gun into the air. Two men are arrested.

Police were kept busy Friday with a spate of crimes that included a carjacking, a man who was firing a weapon into the air, and a fight between two men that left one hospitalized with a gunshot wound.

Police arrested two men, one of whom thought he had been shot by a police officer who fired his weapon at him but missed.

The first incident occurred about 1:30 a.m. when two men with guns demanded the keys to a Chevy Blazer from Michael Madrid at his home in the 600 block of Townsend Street, Police Sgt. Dick Faust said. Madrid handed over his vehicle and called police, who said they issued a statewide bulletin.

About eight hours later, an officer spotted the vehicle about two miles away at 17th Street and Broadway and pursued the assailants, who led police on a short chase, Faust said. The men got out and ran away.

Police spent about an hour looking for them in an apartment complex in the 1000 block of South Parton Street, authorities said.

Marcos Casteneda, 24, of Santa Ana was arrested on suspicion of carjacking after he apparently broke into three apartments while trying to evade police, Lt. Bob Helton said.

“Some people hid in the closet when they heard him break their window with his hand,” Helton said.

He was arrested after one resident alerted police, who surrounded the apartment and took him into custody. Casteneda was treated at Western Medical Center-Santa Ana, where he received several stitches for cuts to his face and legs from breaking windows, investigators said.

Casteneda was being held at the Santa Ana Detention Facility in lieu of $50,000 bail. Detectives recovered a semiautomatic handgun believed to have been used in the car theft. The other suspect is being sought.

In another incident, Carlos Charles Lozano of Santa Ana was arrested on suspicion of discharging a weapon.

The 28-year-old man, who described himself to police as a retired gang member, was riding his bike along the 2100 block of North Candis Avenue about 9:30 a.m. and firing bullets into the air “apparently not aiming at anything,” Helton said. When the man saw a patrol car approaching, he ran “up one street and down the next, doubling back and finally into another police unit,” Helton said.

Police said the man ran toward an officer with his right hand concealed under a light jacket as if holding a weapon or preparing to draw a weapon.

The officer fired one shot and the man fell near the police car, detectives said.

“He apparently thought he had been hit,” Helton said, “but it turns out he was fine.”

Lozano was being held at the Santa Ana Detention Facility in lieu of $50,000 bail. Lozano was arrested on five outstanding warrants that included charges of shooting into a dwelling, assault with a deadly weapon, driving under the influence of drugs or alcohol, and evading arrest, Faust said.

The officer-involved shooting is being investigated by the police internal affairs unit, Faust said.

Later on Friday, another shooting left one man with a gunshot wound that was not life-threatening, police said.

Two men were struggling with a gun in the 1100 block of South Flower Street about 1:30 p.m. when one shot the other once in the chest, Faust said.

The unidentified 20-year-old man was in stable condition at Western Medical Center-Santa Ana. The police’s gang unit is investigating the shooting.

Police said the other man ran away and is being sought.
