Women are under attack in Brooklyn, and police are seeking the public's help in identifying a man wanted for at least two sexual assaults and another man for a string of gunpoint robberies.

According to police, on March 16 at 1 a.m. a 56-year-old woman was approached by an armed suspect near Fulton Street and Franklin Avenue. The suspect took her to John Hancock Park, where he raped her and struck her on the head with his gun. He fled on foot.

On March 23 at 4:40 p.m., at the same intersection, a 42-year-old woman was approached by the suspect, who led her to an alley and produced a gun. The suspect also hit the victim on the head and raped her.

In both cases the victims were black.

The suspect is described as a black man between 25 to 35 years of age, weighing about 160 to 180 lbs and about 5' 6" to 5' 11" tall. In the first assault, the suspect was wearing a green military jacket, black books and brown jeans. In the second assault, the suspect was wearing a green jacket, dark pants and white sneakers.

Police are also searching a man wanted for four gunpoint robberies. In all cases, the victims were older black women from ages 56 to 75.

On March 29, the suspect stuck three times. At 7:14 p.m., police say he robbed his first victim, a 75-year-old woman, inside an elevator at 1114 New York Avenue. He struck her with a silver handgun, then robbed her and fled the scene.

Just three minutes later at 7:57 p.m., the suspect struck again and attacked a 57-year-old woman in the apartment building's lobby. He also struck her in the head with the silver handgun, robbed her and fled the scene.

At 10:38 p.m., about a 1.5 miles away in front of 301 East 48th Street, the suspect hit a 56-year-old woman on the head with the same handgun, robbed her and ran away.

At 6:58 a.m., the following morning, the man approached a 59-year-old woman just one block away from the third attack, at the corner of East 48th Street and Church Avenue.

The woman was hit in the head several times from behind with a black gun. He took the victim's purse and fled the scene.

The first, second and fourth victims suffered minor head injuries. The third victim suffered a cut to her head.

The suspect is described as a black man about 25 years of age with a medium to dark complexion. He is about 6' tall and weighs about 160 to 170 lbs. He was wearing a dark hooded sweatshirt with a white degisn on the back, dark colored jeans and sneakers.
